At basic level, students often have only 'easy' and 'hard' for describing tasks. The exam was easy. The work was hard. But English has several words for different shades of difficulty. 'Simple' is closer to 'easy' but suggests few steps or basic content. 'Straightforward' means clear, with no surprises. 'Difficult' is the everyday word for 'not easy'. 'Hard' is similar to difficult but slightly more casual. 'Tough' is more emphatic and informal. 'Challenging' is more formal and often suggests difficulty that is rewarding. 'Tricky' suggests difficulty caused by complexity or hidden problems. Each fits a different situation. Students who use only 'easy' and 'hard' miss the precision available. This lesson covers the main difficulty words at A2 level.
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.
VERY EASY:
The test was easy. (= not difficult)
The instructions were simple. (= few steps, basic)
The form was straightforward. (= clear, no surprises)
DIFFICULT:
The homework was hard. (= not easy, casual)
The homework was difficult. (= not easy, slightly more formal)
VERY DIFFICULT:
The exam was tough. (= very difficult, casual)
The exam was challenging. (= difficult and demanding, often positive)
The exam was tricky. (= difficult because of hidden problems or details)
Why does English have so many words for difficulty? When does the difference matter?
Each word covers a different shade of difficulty. 'Easy' is the general word for not difficult. 'Simple' suggests few steps or basic content — a simple instruction has only a few parts. 'Straightforward' is about clarity — straightforward tasks have no surprises or hidden complexity. 'Hard' and 'difficult' are very close in meaning — both mean 'not easy', but 'hard' is slightly more casual and 'difficult' slightly more formal. 'Tough' is stronger and more casual — a tough exam was very difficult. 'Challenging' is more positive — it suggests the difficulty is worthwhile, often used in academic or work contexts. 'Tricky' suggests the difficulty comes from complexity or details — a tricky question has parts that look easy but are not. Students who use only easy and hard miss these useful distinctions.
A: A student describes a maths problem with five steps. The steps were clear and the answer came quickly. The problem was ________.
B: A student describes a long final exam. There were many questions, several were unfamiliar, and the time was short. The exam was ________.
C: A teacher assigns a project that requires research and creative thinking. It is difficult but the students find it rewarding. The project is ________.
D: A traveller describes a route that has confusing turns and unmarked junctions. The route was ________.
Which word fits each: simple / tough / challenging / tricky?
Each context fits a specific word. Context A (clear steps, quick answer): 'simple' — few steps, basic, easy. The problem was simple. Could also be 'straightforward' (no surprises) or 'easy'. Context B (long, unfamiliar, time pressure): 'tough' — very difficult and demanding. The exam was tough. 'Hard' or 'difficult' would also work. Context C (rewarding project requiring research): 'challenging' — difficult but worthwhile. The project is challenging. This positive word fits the rewarding aspect. Context D (confusing turns, unmarked junctions): 'tricky' — difficulty caused by complexity or details. The route was tricky. The hidden complexity (unmarked junctions) makes 'tricky' the right word. Each situation calls for a specific word.
This exercise is easy. (= not difficult)
This exercise is simple. (= few steps, basic content)
Learning to read is not easy. (= it is difficult)
Learning to read is not simple. (= it has many steps)
The road from town to the village is easy to follow. (= no problem following it)
The road from town to the village is simple. (= it is one road, no junctions)
Why do students need both words? When does the difference matter?
'Easy' and 'simple' overlap a lot but they emphasise different things. 'Easy' focuses on the lack of difficulty — a task is easy if you can do it without struggling. 'Simple' focuses on the structure or content — a task is simple if it has few parts, few steps, or basic content. A task can be simple but not easy (tying shoelaces is simple but takes practice for a child). A task can be easy but not simple (a complex puzzle that an expert solves quickly is easy for them but the puzzle itself is not simple). For most everyday situations, the words are interchangeable. But for precision: use 'simple' when the structure is basic; use 'easy' when the doing is not hard. Students should know both and choose based on what they want to emphasise.
| Word | Meaning | Register | Example |
|---|---|---|---|
| easy | Not difficult — general | Neutral, any context | The exam was easy — I finished early. |
| simple | Few steps, basic content | Neutral | The instructions are simple — just three steps. |
| straightforward | Clear, no surprises or hidden complexity | Neutral to formal | The form was straightforward — easy to fill in. |
| hard | Not easy — casual | Casual to neutral | The homework was hard — it took me three hours. |
| difficult | Not easy — slightly more formal | Neutral | The science test was difficult — many questions were unfamiliar. |
| tough | Very difficult, casual | Casual | It was a tough exam — many students failed. |
| challenging | Difficult but rewarding, often positive | Neutral to formal | The project was challenging but I learned a lot. |
| tricky | Difficult because of complexity or details | Neutral | The question was tricky — it looked easy but had a hidden trap. |
DISTINCTION 1 — Easy vs simple: Easy means not difficult to do. Simple means few steps or basic structure. The two overlap but emphasise different things. 'An easy task' (not hard to complete). 'A simple task' (few parts). For most tasks both work, but use 'simple' when the structure is basic and 'easy' when the doing is not hard.
DISTINCTION 2 — Hard vs difficult: These are very close in meaning. 'Hard' is slightly more casual; 'difficult' is slightly more formal. 'The exam was hard' (everyday). 'The exam was difficult' (slightly more formal). Both are correct in most contexts. Students can use either.
DISTINCTION 3 — Tough is emphatic: 'Tough' is stronger than 'hard' or 'difficult'. A tough exam is very difficult. A tough situation is hard to manage. The word is informal but commonly used. For dramatic difficulty, 'tough' fits.
DISTINCTION 4 — Challenging is positive: 'Challenging' is the word for difficulty that is rewarding or worthwhile. It is often used in academic and professional contexts. 'A challenging project' suggests it will be demanding but worthwhile. 'A difficult project' is more neutral. Choose 'challenging' for positive framing of difficulty.
DISTINCTION 5 — Tricky for hidden complexity: 'Tricky' suggests difficulty caused by details, complexity, or hidden problems. A tricky question looks easy but has a trap. A tricky situation has unexpected complexity. The word is often used for things that seem simple at first but are actually complicated.
Words for difficulty come up constantly in everyday conversation — describing school work, exams, problems, life situations. Students who know only 'easy' and 'hard' lose the precision available. Cultural context: the word 'challenging' is often used positively, suggesting that difficulty is good for growth. In some contexts, students may avoid this positive framing and stick with 'difficult' or 'hard'. Both are fine. The lesson connects to other near-synonym lessons — students who learn to distinguish shades of meaning in difficulty also learn the general skill of precise word choice.
Use real school work to teach difficulty words. Show three different exercises — one with one step, one with five steps, one with hidden complexity. Ask students to describe each. The first is simple. The second might be challenging. The third is tricky. Real examples make the differences clear and memorable.
Choose the best difficulty word for each situation. Think about whether the difficulty has hidden parts, is rewarding, very strong, or just basic.
Each sentence uses the wrong difficulty word. Suggest a better word and explain.
Use this sequence directly in class — guided discovery, no textbook needed. Tap each step to mark it done.
STEP 1 — Beyond easy and hard (5 min): Ask students to describe the last exam they took, the last project, and the road from their home to school using only 'easy' and 'hard'. Show that this loses precision. Establish that English has many words for difficulty.
STEP 2 — The easy end (5 min): Drill the easy words: easy (general), simple (few steps), straightforward (clear, no surprises). Match each to a context. A maths problem with one step → simple. A clear form → straightforward. A test you finished early → easy. Practise five examples.
STEP 3 — The difficult end (8 min): Drill the difficult words. Hard (casual not easy), difficult (slightly more formal), tough (very difficult, casual), challenging (difficult but rewarding), tricky (difficulty from hidden complexity). Match each to a context: a long exam → tough. A demanding rewarding project → challenging. A maths problem with a trap → tricky. A formal report context → difficult. Practise.
STEP 4 — The challenging vs tough distinction (5 min): Spend focused time on this important difference. Challenging is positive — it suggests rewarding difficulty. Tough is negative — just very difficult, often unpleasant. Practise with five contexts: rewarding work (challenging), bad job (tough), demanding course you enjoy (challenging), exhausting day (tough). Drill the difference.
STEP 5 — Describe your week (4 min): Each student describes three things from their week using three different difficulty words. The exam was tough. The new chapter was challenging. The instructions were straightforward. Share in pairs. Partner checks: did the words fit?
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.
