Some of the most common English structures involve a verb, then an object (a person), then an infinitive — 'I want her to explain', 'She asked us to stay'. This pattern is extremely frequent in everyday communication but causes persistent errors because students either omit the 'to', keep the 'to' where it should not be, or confuse the object position. This lesson also covers the bare infinitive (without 'to') — which appears after make, let, help, and perception verbs.
Before you start — think honestly about your own teaching and experience.
Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.
Read these sentences. All of them have a verb, then a person, then an infinitive. What is the structure?
The structure is: Verb + Object (person) + to + infinitive. 'She wants (him) (to study)'. The subject performs the first verb (wants, asked, told). The object (him, all staff, her, you, the students, her) is the person who will perform the second action. Between them: to + infinitive. This pattern is extremely common and natural in English. Many students try to use a 'that' clause instead: 'She wants that he studies harder.' While this is used in other languages and some varieties of English, standard written English strongly prefers the object + infinitive pattern. 'I want you to come' — not 'I want that you come.''
Now look at these sentences. The structure is similar — but something is different about the second verb. What has changed?
After make, let, and help (informally), the infinitive appears WITHOUT 'to'. This is called the BARE INFINITIVE — just the base form of the verb, without 'to'. 'Make + object + bare infinitive': She made them sit. 'Let + object + bare infinitive': She let them play. 'Help + object + bare infinitive (or to + infinitive)': He helped her find / to find. Make is the most important: it always takes the bare infinitive in the active voice. Let also always takes the bare infinitive. Help can take either the bare infinitive or to + infinitive — both are accepted. This difference — to after ask/tell/want but bare after make/let — is a very common source of error.'
Now read these sentences with adjectives. What form follows the adjective in each case?
Adjectives that describe feelings, difficulty, readiness, or evaluation are commonly followed by 'to + infinitive'. 'Happy to help' (feelings). 'Difficult to pass' (evaluation). 'Ready to begin' (readiness). 'It is wonderful to see' (using 'it' as a dummy subject). Two main structures: (1) She is happy to help. (subject + adjective + to + infinitive — she is the one helping) (2) It is difficult to manage a large class. ('It' is a dummy subject — nobody specific is managing; the 'to' clause is the real subject). Both are extremely common. This is a reliable pattern — adjective + to + infinitive — with very few exceptions.'
THE MAKE PASSIVE — an important structural shift:
When 'make' is passive (in a passive sentence), 'to' RETURNS to the infinitive:
Active: The teacher made the students write it again. (bare infinitive — no 'to')
Passive: The students were made to write it again. ('to' returns)
This is a common point of confusion — students learn 'make = bare infinitive' and then write 'He was made work again' without 'to'. The rule: bare infinitive in the active, to + infinitive in the passive.
THE 'WANT THAT' PROBLEM — extremely common across many L1 backgrounds:
In many languages, the equivalent of 'I want that she comes' is grammatically standard. In standard formal English, this construction is avoided:
Does the verb take a person before the infinitive? → verb + object + to + infinitive (want her to come). Is the verb 'make' or 'let'? → bare infinitive — no 'to'. Is the verb 'help'? → bare or to + infinitive, both fine. Is the main clause passive with 'make'? → 'to' returns (was made to do). Is there an adjective before the infinitive? → adjective + to + infinitive (easy to understand, happy to help).
Choose the correct form. Think carefully about which verb pattern is being used.
Each sentence contains an error. Write the correct version and explain why — then reveal the answer.
Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.
STEP 1 — VERB + OBJECT + INFINITIVE (8 minutes): Write these sentence frames on the board. Students complete them about real classroom situations.
STEP 2 — MAKE AND LET: NO 'TO' (8 minutes): Contrast explicitly:
STEP 3 — ADJECTIVE + TO + INFINITIVE (5 minutes): Write five sentence frames. Students complete with a real idea.
STEP 4 — PERCEPTION VERBS (5 minutes): Demonstrate the difference between bare infinitive and -ing after see, hear, watch.
STEP 5 — ERROR HUNT (5 minutes): Write five sentences — some correct, some wrong. Focus especially on 'made them to sit', 'was made sit', and 'want that she comes'. Students correct in pairs and name the rule.
Use directly in class — copy, adapt, or read aloud. No printing needed.
For each strategy, choose the option that best describes where you are now.
