Learning Words Through Their Mistakes
Studies show learners who explicitly study common errors alongside correct usage retain the right form better than learners who study only the correct form. The error highlights why the correct form is correct. Each card here pairs one frequent ESL mistake with the correction and a one-line explanation.
How to Use the Mistake Cards
When you flip the card, read both the wrong form and the correct form aloud. Then read the explanation. The contrast cements the correct version more efficiently than memorising the right form alone. Two passes through this deck — once to recognise the mistake, once to produce the correction — covers most ESL grammar potholes.

FAQ
How is this collection assembled?
Cards are selected by a metadata query against the dictionary — for example, "irregular-verbs" pulls every entry where the verb_conjugation field has is_irregular = true. The deck stays current automatically as new dictionary entries publish.
Should I study this before or after CEFR levels?
Use collections as a focused supplement, not a replacement. Build your CEFR foundation first, then drill collections to plug gaps. The "Irregular Verbs" collection in particular is worth doing in parallel with A1 and A2 — most irregulars are top-1k words.
Why are some entries missing?
The dictionary publishes entries in tiered batches. Specialist or rare entries may not have been added yet. Check back as new batches publish.
