How to Remember English Words: Spaced Repetition and Quizzes
Short answer: you forget new words because you meet them once and never have to pull them out of memory again. Fix it with two habits: review each word at growing gaps (for example 1, 3, 7, 14, 30 and 60 days after you learn it, and tomorrow if you got it wrong), and test yourself instead of rereading. Ten minutes a day of this beats an hour of cramming once a week.
Why new words disappear
Psychologists have studied forgetting since the 1880s, when Hermann Ebbinghaus measured how quickly he forgot lists he had memorised. The pattern he described, often called the forgetting curve, is now familiar to every language learner: most of what you learn in one sitting fades fast in the first days, and then the rest fades more slowly. Each time you successfully recall the item again, it fades more slowly than before.
Vocabulary has a few extra traps:
- Recognition is not recall. Reading a list and thinking "yes, I know that" feels like progress, but in Writing you have to produce the word from nothing. Those are different skills.
- Similar words interfere. Affect and effect, adapt and adopt, economic and economical blur together if you only see them once.
- Words learned without context have nothing to hang on. A translation alone gives you one thread to the word; an example sentence, a topic and a sound give you several.
Spaced review: the timing fix
The idea of spaced repetition is simple. Review a word just before you would forget it. Each time you recall it correctly, wait longer before the next review. Each time you fail, bring it back soon. A practical schedule:
- Day 0: learn the word.
- Day 1, 3, 7, 14, 30 and 60: review it. If you still know it, move to the next gap.
- Any miss: back tomorrow, then climb the gaps again.
This spreads your effort. Words you know well cost almost nothing after a month, while hard words get the extra attention they need. It also keeps daily work predictable, which matters when you have a test date coming.
Quizzes: the effort fix
Research on the "testing effect" shows that trying to retrieve something strengthens memory more than studying it again. Struggling to remember mitigate and then seeing the answer teaches more than reading mitigate = reduce harm a fifth time. Good vocabulary quizzes:
- Go in more than one direction: meaning to word (the Writing direction), word to meaning (the Reading direction) and fill-in-the-blank (the grammar and context).
- Shuffle the choices, so you learn the word, not the position of the right answer.
- Are short: ten questions is enough to find the weak words without becoming a chore.
- Feed back into review: a word you miss in a quiz should come back soon, not wait for its next scheduled date.
Make each word richer
When you first meet a word, give your memory more than one hook. Read an easy English meaning, check the translation in your own language so there is no doubt, read an example sentence on a familiar topic, and say it aloud after hearing the pronunciation. For IELTS, examples on essay topics such as the environment, technology or education are doubly useful: you remember the word and a way to use it.
A ten-minute daily routine
- Do today's reviews first, including yesterday's misses.
- Learn today's new words with meaning, example and sound.
- Take one short quiz.
- Keep the streak alive on busy days by doing only the reviews.

Bandlio builds this routine around 950 academic words for IELTS. On each card you tap "I know it" or "Again": known words come back after 1, 3, 7, 14, 30 and 60 days, and missed words come back tomorrow. Ten-question quizzes ask meaning to word, word to translation and fill-in-the-blank with shuffled choices, and missed quiz words go back to review. Each card has an easy English meaning, a translation in your language (24 built in, offline), an example sentence on an IELTS essay topic and British or American pronunciation through your phone's text-to-speech. A streak, progress out of 950 and a home screen widget with today's word keep you coming back. No account; everything stays on your phone.
Frequently asked questions
Why do I forget English words so quickly?
Memory for a new word fades quickly unless you use it or recall it again. Seeing a word once, or rereading a list, gives a feeling of knowing without building strong recall. Coming back to the word at growing gaps and testing yourself on it is what slows the forgetting.
What are good review intervals?
A common pattern is 1, 3, 7, 14, 30 and 60 days after you first learn a word, with any word you get wrong coming back the next day. The exact numbers matter less than the idea: each successful recall earns a longer gap.
Is it better to reread words or quiz myself?
Quiz yourself. Trying to recall a word, even when you fail, strengthens memory more than reading the answer again. Mix the direction: meaning to word, word to meaning and filling it into a sentence.
