Double Letters: When to Double Consonants in Verb Forms

What this session covers

In English, when we add -ing or -ed to a verb, sometimes we double the final consonant and sometimes we do not. 'Run' becomes 'running' (double n). 'Swim' becomes 'swimming' (double m). 'Plan' becomes 'planned' (double n). But 'hope' becomes 'hoping' (no double, drop the e). 'Write' becomes 'writing' (drop the e, no double). 'Visit' becomes 'visiting' (no double). The rule depends on the structure of the verb. Verbs with one syllable that end in one vowel + one consonant (like run, swim, stop) double the consonant. Verbs ending in -e drop the -e. Other verbs just add -ing or -ed without changes. Students who do not know the rules produce errors like 'runing' (missing the double) or 'hopeing' (keeping the e). This lesson covers the main double-letter spelling rules at A2 level.

Personal Reflection

Before you start — think honestly about your own teaching and experience.

Q1
When your students write 'runing' instead of 'running' or 'hopeing' instead of 'hoping', do they know there are rules for when to double consonants — or do they guess?
Q2
Which of these have you seen your students get wrong or avoid using altogether?

Discover the Pattern

Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.

1
Some verbs double the final consonant:

run + ing = running (double n)
swim + ing = swimming (double m)
stop + ed = stopped (double p)
plan + ed = planned (double n)
begin + ing = beginning (double n)
shop + ing = shopping (double p)

What do these verbs have in common? Why does English double the consonant?

All these verbs share a structure: one syllable (or stress on the last syllable), ending in one vowel + one consonant. Run = r-u-n (one vowel u, one final consonant n). Swim = s-w-i-m. Stop = s-t-o-p. Plan = p-l-a-n. The doubling shows that the vowel sound stays short. Without doubling, English readers would expect a long vowel sound — 'runing' would suggest 'roo-ning' (long u). Doubling the n gives 'running' — keeping the short u sound. The rule is: one syllable + one vowel + one consonant → double the consonant before adding -ing or -ed. Begin doubles too (beginning) because the stress is on 'gin' — the last syllable. Most one-syllable verbs of this type follow the rule. Students who learn this rule can spell many verb forms correctly without memorising each one.

2
Verbs ending in -e drop the e:

hope + ing = hoping (drop the e)
write + ing = writing (drop the e)
live + ing = living (drop the e)
dance + ing = dancing (drop the e)
arrive + ed = arrived (the e becomes part of -ed)
love + ed = loved

Why do these verbs drop the e? What rule are they following?

Verbs ending in -e drop the e before adding -ing. Hope + ing = hoping (not 'hopeing'). Write + ing = writing (not 'writeing'). Live + ing = living. The rule is simple: silent -e at the end + ing → drop the -e. The same rule applies for -ed in some cases — but more often the -e and -ed combine: arrive + ed = arrived (the e of arrive is replaced by -ed; or you can think of it as just adding -d). Hope + ed = hoped. Live + ed = lived. The visual rule for -e endings: drop the e, then add the suffix. Students who do not know this rule write 'hopeing' or 'writeing' or 'liveing' — all wrong. Drilling this rule fixes a common spelling problem.

3
Verbs that DO NOT double:

visit + ing = visiting (no double — visit has TWO syllables and stress is on the FIRST)
open + ing = opening (no double — same reason)
happen + ed = happened (no double — same reason)
listen + ing = listening (no double — same reason)
rain + ing = raining (no double — TWO vowels: a-i, not one)
shout + ing = shouting (no double — TWO vowels: o-u)
look + ing = looking (no double — TWO vowels: o-o)

What are the patterns of NO doubling? When does English NOT double the consonant?

Verbs do NOT double the consonant when the word does not fit the one-syllable + one vowel + one consonant pattern. Two reasons for not doubling: (1) Two-syllable verbs with stress on the FIRST syllable do not double — visit, open, happen, listen. The rule for two-syllable verbs is more complex (sometimes they double if the stress is on the last syllable — like begin → beginning), but at A2 level the safe rule is: most two-syllable verbs do NOT double. (2) Verbs with two vowels before the final consonant do not double — rain (a-i), shout (o-u), look (o-o), reach (e-a). The two vowels signal a long vowel sound, which does not need doubling to stay short. The combined rule for A2 students: only double when the verb is one syllable AND ends in one vowel + one consonant. Otherwise, just add -ing or -ed.

The Pattern — What You Just Discovered

Three main spelling rules apply when adding -ing or -ed to verbs. Rule 1 — Double the final consonant when the verb is one syllable AND ends in one vowel + one consonant (run → running, stop → stopped, plan → planned). Rule 2 — Drop the -e when the verb ends in -e (hope → hoping, write → writing, live → living). Rule 3 — Just add -ing or -ed for everything else (visit → visiting, look → looking, rain → raining). Knowing the rules helps students spell verb forms correctly and avoid the most common errors.
Rule When Examples Notes
Double the consonant One syllable + one vowel + one consonant run → running, stop → stopped, plan → planned, swim → swimming, hop → hopping The doubling keeps the vowel sound short.
Drop the -e Verbs ending in silent -e hope → hoping, write → writing, live → living, dance → dancing, love → loving Drop the -e before -ing. For -ed, the e becomes -ed (hope → hoped).
Just add -ing or -ed Verbs that do not fit the other rules visit → visiting, open → opening, look → looking, rain → raining, shout → shouting For two-syllable verbs (stress on first syllable) and verbs with two vowels before the consonant.
Two vowels — no double Verbs with two vowels before the final consonant rain → raining (a-i), look → looking (o-o), shout → shouting (o-u), reach → reaching (e-a) Two vowels mean a long vowel sound — no doubling needed.
-y → -ying or -ied Verbs ending in -y after a consonant try → tried (y → i + ed), study → studying / studied (y stays before ing, becomes ied for past) Special pattern for -y endings. -ying for present, -ied for past.
Two-syllable, stress on last Some two-syllable verbs DO double (when stress is on the last syllable) begin → beginning (stress on 'gin'), prefer → preferred, occur → occurred Less common pattern. Mostly memorised. begin/begun are key examples.
Common errors Errors students make from not knowing the rules runing ✗ (should be running) | hopeing ✗ (should be hoping) | visitting ✗ (should be visiting) | studing ✗ (should be studying) All common errors. The rules above prevent them.
Suffix Patterns

PATTERN 1 — Double the consonant: When a verb is one syllable AND ends in one vowel + one consonant, double the final consonant before -ing or -ed. Run → running. Stop → stopped. Plan → planned. Swim → swimming. The doubling keeps the vowel sound short.

PATTERN 2 — Drop the -e: When a verb ends in silent -e, drop the -e before adding -ing. Hope → hoping. Write → writing. Live → living. For -ed, the e combines with the suffix: hope → hoped, live → lived.

PATTERN 3 — Just add -ing or -ed: Most other verbs just add -ing or -ed without changes. Visit → visiting / visited. Open → opening / opened. Look → looking / looked. Rain → raining / rained. The default rule for verbs that do not fit the doubling or e-dropping patterns.

PATTERN 4 — Two vowels = no double: Verbs with two vowels before the final consonant do not double. Rain has a-i, look has o-o, shout has o-u, reach has e-a. The two vowels signal a long vowel sound that does not need doubling to stay short.

PATTERN 5 — Two syllables = usually no double: Most two-syllable verbs with stress on the first syllable do not double. Visit, open, listen, happen, gather. Just add -ing or -ed: visiting, opening, listening, happened.

PATTERN 6 — The -y rule: Verbs ending in -y after a consonant follow a special rule. For -ing, the y stays: study → studying, try → trying. For -ed, y changes to i: study → studied, try → tried. After a vowel, no change: play → played.

PATTERN 7 — Drilling the most common errors: The most common errors are 'runing' (missing the double n in running), 'hopeing' (keeping the e in hoping), 'visitting' (doubling when it should not), 'studing' (missing the y in studying). Drilling these errors with the correct forms fixes them.

Note

Spelling rules for verb forms are essential at A2 level. Students who do not know the rules produce errors that are very visible in writing. The good news is that the rules are small and learnable. The bad news is that English has exceptions and edge cases. For A2 students, the safe approach is: learn the three main rules (double, drop -e, just add) and the most common verbs in each category. Reading and writing regularly helps fix the spellings. The rules connect to the gerunds and infinitives lesson (#47) — students who know which verbs take -ing also need to spell those -ing forms correctly. The lesson also connects to irregular verbs (#38) — the regular verb form rules apply only to regular verbs.

💡

Build a spelling wall with three columns: DOUBLE (run → running), DROP E (hope → hoping), JUST ADD (visit → visiting). Add verbs as students meet them in reading. Drill the rules through fast oral practice — the teacher says a base verb, students give the -ing form. Speed forces automatic spelling.

Common Student Errors

I am runing in the park every morning before school.
I am running in the park every morning before school.
Why'Run' is one syllable, ends in one vowel + one consonant (u + n). The rule says double the consonant before -ing: running. 'Runing' is a very common spelling error. Always 'running' (with double n).
She is hopeing for a good result on her exam tomorrow.
She is hoping for a good result on her exam tomorrow.
Why'Hope' ends in silent -e. The rule says drop the -e before -ing: hoping. 'Hopeing' is wrong. Always drop the e. The same applies to write → writing, live → living, dance → dancing.
We are visitting our grandmother this weekend at her house.
We are visiting our grandmother this weekend at her house.
Why'Visit' is two syllables with stress on the first (VIS-it). Two-syllable verbs with first-syllable stress do not double the consonant. Just add -ing: visiting. 'Visitting' is over-doubling.
She is studing very hard for her final exams.
She is studying very hard for her final exams.
Why'Study' ends in -y after a consonant. For -ing, the y stays: studying. The error 'studing' drops the y, which is wrong. The y stays for -ing forms; it changes to i only for -ed forms (studied).
It was rainning heavily all afternoon yesterday.
It was raining heavily all afternoon yesterday.
Why'Rain' has two vowels (a-i) before the final consonant. Verbs with two vowels before the consonant do NOT double. Just add -ing: raining. The two-vowel pattern signals a long vowel sound which does not need doubling. The same applies to look → looking, shout → shouting, reach → reaching.

Check Your Understanding — Part 2: Why Is It Wrong?

Each sentence has a spelling error in the verb form. Find the wrong form, write the correct one, and explain.

The children were swiming in the river yesterday afternoon.
Write the correct sentence:
Explain why it is wrong:
The children were swimming in the river yesterday afternoon.
Swim is one syllable, ends in one vowel (i) + one consonant (m). The rule says double the consonant before -ing: swimming. 'Swiming' misses the double m. Always 'swimming' (with double m).
She is liveing in the next village now since she got married.
Write the correct sentence:
Explain why it is wrong:
She is living in the next village now since she got married.
Live ends in silent -e. The rule says drop the -e before -ing: living. 'Liveing' keeps the e, which is wrong. Always drop the e. Same applies to come → coming, take → taking, give → giving.
My mother is openning the shop at six o'clock every morning.
Write the correct sentence:
Explain why it is wrong:
My mother is opening the shop at six o'clock every morning.
Open is two syllables with stress on the first syllable (O-pen). Two-syllable verbs with first-syllable stress do not double the consonant. Just add -ing: opening. 'Openning' over-doubles.
It was raning heavily last night and I could not sleep.
Write the correct sentence:
Explain why it is wrong:
It was raining heavily last night and I could not sleep.
Rain has two vowels (a-i) before the final consonant n. Verbs with two vowels before the consonant do not double. Just add -ing: raining. 'Raning' might come from confusing rain with verbs like run.

Classroom Teaching Sequence

Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.

0 / 5 done
1

STEP 1 — Why the rules matter (4 min): Write three verb pairs on the board: run → running, hope → hoping, visit → visiting. Show that each pair follows a different rule. Establish that English has spelling rules for verb forms — knowing them prevents very common errors.

2

STEP 2 — The doubling rule (6 min): Drill the doubling rule. One syllable + one vowel + one consonant → double. Show: run → running, stop → stopped, plan → planned, swim → swimming. Practise five verbs. Check: does each fit the pattern? Yes → double.

3

STEP 3 — The drop-the-e rule (5 min): Drill the e-dropping rule. Verbs ending in silent -e → drop the e. Show: hope → hoping, write → writing, live → living, dance → dancing. Practise five verbs. The pattern: -e → drop, add -ing.

4

STEP 4 — The default rule (5 min): Show that other verbs just add -ing or -ed without changes. Two-syllable verbs (visit → visiting, open → opening). Two-vowel verbs (rain → raining, look → looking). Establish that this is the default — most verbs follow it. Only the doubling and dropping rules are exceptions.

5

STEP 5 — Quick spelling drill (5 min): Call out base verbs at speed. Students write the -ing forms. Mix all three rules — doubling, dropping, no change. After ten verbs, check spellings. Discuss errors. Speed and repetition fix the rules in memory.

Ready-to-Use Classroom Materials

Use directly in class — copy, adapt, or read aloud. No printing needed.

1 Three-rule wall (display)
Create a wall display with three columns: DOUBLE / DROP -E / JUST ADD. Add verbs as students meet them. The visual organisation makes the rules clear and memorable.
Example sentences
DOUBLE: run → running, stop → stopped, plan → planned, swim → swimming, hop → hopping, sit → sitting
DROP -E: hope → hoping, write → writing, live → living, dance → dancing, love → loving, take → taking
JUST ADD: visit → visiting, open → opening, listen → listening, look → looking, rain → raining, shout → shouting
2 Quick spelling drill (oral and written)
Call out a base verb. Students write or say the -ing form. Move quickly. Mix verbs from all three categories. Check spellings and discuss errors immediately.
Example sentences
Teacher: 'run' → Student writes 'running' (double)
Teacher: 'hope' → Student: 'hoping' (drop e)
Teacher: 'visit' → Student: 'visiting' (just add)
Teacher: 'study' → Student: 'studying' (y stays)
Teacher: 'swim' → Student: 'swimming' (double)
Teacher: 'rain' → Student: 'raining' (just add)
3 Spell the sentence (writing)
Read out a sentence with verb forms. Students write the sentence with correct spelling. Common errors: missing doubles, keeping silent -e, over-doubling. Mark errors and discuss the rule.
Example sentences
Teacher dictation: 'I am running and swimming every day, and hoping to win.' → Student writes carefully — running (double), swimming (double), hoping (drop e)
'She is visiting her family and looking after the children.' → visiting (just add), looking (just add)

Plan Your Next Steps

For each strategy, choose the option that best describes where you are now.

Build the spelling vocabulary further with more rules: -y to -ies for plural nouns (baby → babies — covered in #11), -y to -ier for comparatives (happy → happier — covered in #12), -e to -ing in different contexts.
Connect to gerunds and infinitives (#47). Students who know which verbs take -ing also need to spell those -ing forms correctly. The two lessons work together.
Look at common spelling exceptions: travel → travelling (British) vs traveling (American). Such exceptions exist and students should know about them.
Teach the three-syllable rule for two-syllable verbs: prefer → preferred (stress on second), enter → entered (stress on first, no double). The stress rule is more advanced but useful at B1.
Ask students to keep a spelling notebook. Each new verb form they learn, they note which rule it follows. Reviewing weekly fixes the rules in memory.
What is the one change you will make next time you teach this vocabulary?

Key Takeaways

1 English has three main spelling rules for verb forms (-ing and -ed). Rule 1 — Double the consonant when the verb is one syllable + one vowel + one consonant (run → running). Rule 2 — Drop the -e when the verb ends in silent -e (hope → hoping). Rule 3 — Just add -ing or -ed for everything else (visit → visiting).
2 The doubling rule keeps the short vowel sound. Without doubling, English readers would expect a long vowel sound. 'Runing' would suggest 'roo-ning' instead of the correct 'run-ning'.
3 Verbs with two vowels before the final consonant do not double — the two vowels already signal a long sound (rain → raining, look → looking, shout → shouting).
4 Verbs ending in -y after a consonant: y stays for -ing (study → studying), y changes to i for -ed (study → studied). After a vowel, no change (play → played).
5 The most common errors are missing doubles ('runing' for running), keeping silent -e ('hopeing' for hoping), and over-doubling ('visitting' for visiting). Drilling the three rules prevents these errors.
