The best way to learn English vocabulary is to study common words first, learn them in short sentences, and review them at growing intervals so you remember them for months, not days.
Most learners know the feeling. You study fifty new words on Sunday, and by Wednesday half of them are gone. That is not a sign that you are bad at languages. It is how memory works. The fix is not more effort, but a better method.
Key takeaways
- Learn the most useful words first; do not start with rare ones.
- Study words inside short sentences, not as isolated translations.
- Use spaced repetition: review just before you forget.
- Say and write the word, not only read it.
- Keep new words per day small, but review every day.
Start with the right words
English has hundreds of thousands of words, but you do not need most of them. A few thousand common words cover the large majority of everyday reading and speech. So the order in which you learn matters more than the total.
This is why we organise vocabulary by CEFR level. Words at A1 and A2 are the most frequent and useful. B1 and B2 words add detail and flexibility. C1 and C2 words are rarer and often more formal. You can look up the level of any word in our CEFR dictionary, which covers 9,337 words.
A simple rule: if you meet a word once, ignore it. If you meet it three times in a week, learn it. Frequency is a good signal that a word is worth your time.
Learn words in context
A word alone is a weak memory. A word in a sentence is a strong one. Instead of writing «book = libro», write «I need to book a table for Friday.» Now you remember the meaning, the grammar and a usable phrase.
Pay special attention to collocations, which are words that go together. We say «make a decision» but «do homework», «heavy rain» but not «strong rain». Natural English is built from these pairs. When you learn a new word, also write down one or two words it often travels with.
Do not forget multi-word items. Phrasal verbs such as «give up» or «look after» behave like single words and are very common. Our phrasal verbs section groups them by level so you can learn them in a sensible order.
Use spaced repetition
Psychologists have known for over a century that we forget new information quickly, then more slowly. Reviewing it at the right moment makes the memory stronger and the gap before the next review longer. This is called spaced repetition.
In practice, it looks like this: see a new word today, again tomorrow, then in three days, then in a week, then in a month. Words you find easy move to longer gaps. Words you miss come back sooner.
You can do this with paper cards in boxes, or you can let an app schedule it. Our daily practice uses spaced repetition, so you only see what you need to review today. Even ten minutes a day is enough to keep a few hundred words alive.
Make every word active
Recognising a word when you read it is easy. Using it when you speak is much harder. To move words from «passive» to «active» knowledge, you need to produce them.
- Say the word aloud in a sentence.
- Write one sentence about your own life with the new word.
- Cover the translation and try to recall the English word.
- Use the word in a short message or a diary line the same day.
Pictures and sound can help too. For concrete words such as «kettle» or «ladder», imagine the object or look at a photo instead of translating it. For abstract words such as «reliable», think of a person you know who fits the word. Your brain keeps stories and images longer than plain definitions. Even a quick mental picture adds a second path back to the word.
Personal sentences work especially well. «My brother is very stubborn» is easier to remember than a dictionary example about a stranger.
A simple daily routine
Here is a plan that takes about 20 minutes.
- Review (8–10 minutes). Do your spaced repetition cards for today.
- Learn (5 minutes). Add 5 to 10 new words from your level. No more.
- Read or listen (5 minutes). Find those words again in a short text. Graded texts in our reading section are written to reuse words at your level.
- Use (2 minutes). Write one sentence with a new word.
Five new words a day is about 150 words in a month and over 1,800 in a year. That is a real change, and it is far more reliable than learning 100 words in one night.
Common mistakes to avoid
- Learning too many words at once. You will forget most of them.
- Using only translation. Add a simple English definition or example when possible.
- Skipping review. New words without review are mostly wasted.
- Ignoring pronunciation. Check how the word sounds; English spelling can mislead.
- Never meeting the word again. Read and listen so that the words come back naturally.
If a word refuses to stick, do not blame yourself. Change something: a new example, a picture, a short story with the word, or a link to a similar word in your own language. Then try again after a day.
How many words do I need to know?
A rough guide: about 2,000 common words let you handle many everyday situations, and 5,000–8,000 help you read general texts comfortably. But the exact number depends on your goals.
Should I learn words from a list or from reading?
Both help. Lists give you a fast start with the most useful words, and reading shows you how they work in real sentences. A mix is best.
What is the best time to review?
Short daily sessions are best. Many people like the morning or the commute, but the best time is the one you will keep.
Do flashcards really work?
Yes, if you use them with spaced repetition and with sentences, not just single words. Flashcards alone, without reading and listening, are not enough.
