You learn a new English word. You write it down, maybe even repeat it a few times. For a couple of days, you feel like you've finally got it.

Then someone uses that word in a conversation - and suddenly, nothing.

You know you've seen it before. You might even remember what it means. But when you try to say it yourself, your brain offers absolutely nothing.

Why do I keep forgetting English words? If this sounds familiar, you're definitely not alone. Forgetting vocabulary is a normal part of learning a language. The problem is usually not that your memory is bad. More often, it's how you learn and practise new words.

The good news? A few simple changes can make it much easier to remember vocabulary and, even more importantly, actually use it when speaking.

Why do I keep forgetting English words?

There are several reasons why a word that seemed easy yesterday can disappear today.

You recognise the word, but don't actively remember it

There's an important difference between recognising a word and being able to recall it.

For example, you might read:

She was exhausted after work.

and immediately understand that exhausted means very tired.

But if you're talking to someone and want to say "Byłem wykończony po pracy", can you produce exhausted without seeing it first?

This is why simply reading vocabulary lists isn't always enough. Recognition is easier than recall.

You learn too many words at once

It's tempting to create a list of 30 or 50 new words and try to memorise all of them.

The problem is that most of those words probably won't appear again for quite a while.

Instead of trying to memorise everything, choose a smaller number of words that are useful for your life, work or current level.

Five words that you actually use are often more valuable than 30 words that you forget a week later.

You don't use new vocabulary

Imagine learning the word deadline on Monday and never seeing or saying it again.

A week later, it's gone.

Now imagine that you use it several times:

I have a deadline on Friday.
We need to meet the deadline.
The deadline has been moved to Monday.

The word starts to become familiar because your brain has seen it in different situations.

Learning a word is only the beginning. Using it is what helps make it available when you need it.

You learn isolated words instead of phrases

Another common problem is learning vocabulary like this:

decision = decyzja

It's correct, but not necessarily very useful.

It's often better to learn a word together with the phrases you are likely to use:

make a decision
a difficult decision
make the right decision

This gives you something much closer to the way vocabulary actually works in real conversations.

7 practical tips to remember English words

So, what can you actually do differently?

1. Stop trying to memorise every word

You don't need to remember every unfamiliar word you encounter.

When you're reading or watching something in English, ask yourself:

"Will I actually use this word?"

Prioritise vocabulary that is:

• useful in everyday conversations
• relevant to your work or studies
• connected to your interests
• common enough to appear regularly
• something you repeatedly encounter

For example, if you work in marketing, learning words such as campaign, target audience, engagement and conversion may be much more useful than memorising random vocabulary from a general word list.

The goal isn't to build the biggest vocabulary possible. It's to build a vocabulary you can actually use.

2. Learn words in context

Instead of memorising:

avoid = unikać

learn a sentence:

I try to avoid checking my phone before bed.

Now you know what the word means, how it works in a sentence and what words commonly appear around it.

Even better, make the sentence relevant to you:

I avoid working late on Fridays.

Personal connections can make vocabulary easier to remember because you're no longer learning a completely abstract example.

Try this

Whenever you learn a new word, write down:

The word: avoid
A useful phrase: avoid doing something
Your sentence: I try to avoid working at weekends.

That's already much more useful than a translation in a vocabulary list.

3. Use active recall

One of the simplest ways to make vocabulary stick is to test yourself instead of just looking at the answer.

For example, don't read:

to improve = poprawić / ulepszyć

and move on.

Cover the translation and ask yourself:

"How do I say 'poprawić' in English?"

Wait a few seconds and try to remember.

If you can't, look at the answer and try again later.

You can do this with flashcards, an app, a notebook or even a piece of paper.

The important part is the effort of retrieving the word from memory.

4. Come back to words after a few days

You don't have to study the same vocabulary for an hour every day.

In fact, short sessions spread over time can be much easier to fit into your routine.

For example:

Monday: learn 5 new words
Tuesday: quickly test yourself
Thursday: use the words in sentences
Sunday: review them again

Then repeat the process with new vocabulary.

This is often called spaced repetition: instead of trying to learn something once and remember it forever, you return to it at intervals.

And don't panic if you forget something during a review. Having to retrieve a word again is part of the learning process.

5. Say the words out loud

If your main goal is to speak English, don't keep your vocabulary practice completely silent.

When you learn a new expression, say it.

Then use it in a few different sentences.

For example, you're learning get used to:

I'm getting used to working from home.
It took me a while to get used to the weather.
You'll get used to speaking English.

You don't need to create complicated sentences. The important thing is to make the word part of something you can actually say.

This is particularly useful for learners who can understand English quite well but struggle to find the right words during conversations.

6. Keep an "English words I keep forgetting" list

Here's a slightly different approach: don't only record the new words you're learning.

Record the words you keep forgetting.

Maybe you have seen appointment twenty times but still can't remember it when you need it. Put it on the list.

The same goes for words you regularly confuse:

borrow / lend
say / tell
remember / remind
job / work

These are worth extra attention because they're clearly causing you problems.

You could even divide your vocabulary notebook into two sections:

New words

and

Words I keep forgetting

The second list can be surprisingly useful.

7. Use new vocabulary in real conversations

This is probably the biggest step between "I know this word" and "I can actually use this word."

Try to use new vocabulary when speaking, even if it feels slightly unnatural at first.

For example, you've recently learned:

I'm looking forward to...

Don't just recognise it when you see it. Find a reason to say:

I'm looking forward to the weekend.

or:

I'm looking forward to my holiday.

or:

I'm really looking forward to seeing my friends.

The more often you retrieve a word in real situations, the less likely you are to freeze when you need it.

And this is one reason speaking practice matters so much when learning vocabulary. A conversation forces you to find the words yourself, rather than simply recognising them on a page.

What if you forget a word while speaking?

This happens even to advanced learners.

You're in the middle of a sentence and suddenly:

"I went to this... um... place where you can..."

You know the word. It's right there somewhere. You just can't access it.

Don't immediately switch to your native language.

Try describing the word instead.

If you've forgotten pharmacy, you could say:

"The place where you buy medicine."

If you've forgotten receipt:

"The piece of paper you get after you pay for something."

This is actually a valuable communication skill. You don't need to know every word to have a successful conversation.

And sometimes, after you've explained the word, you'll suddenly remember it:

"The place where you buy medicine... pharmacy! That's it."

That moment of retrieval can make the word much more memorable next time.

How many English words should you learn at once?

There's no magic number that works for everyone.

If you regularly forget new vocabulary, however, it may be worth reducing the amount rather than increasing it.

Instead of learning 20 new words every day, try five useful words and spend more time doing something with them.

For example:

5 words × 3 sentences each = 15 sentences

That's much more meaningful practice than reading a list of 20 translations once.

You can also choose vocabulary around one topic. If you're travelling, learn useful travel phrases. If you're preparing for a job interview, focus on language you are likely to need during the interview.

Your vocabulary study should reflect what you actually want to do in English.

A simple 15-minute vocabulary routine

If you don't know where to start, try this:

Minutes 1–5: Review

Take five words you've learned recently.

Cover the translations and try to remember them.

Minutes 6–10: Use them

Create one sentence for each word.

Better still, say the sentences out loud.

Minutes 11–15: Connect them to your life

Ask yourself:

Where could I use this word?

Try to create a sentence about your work, hobbies, family, travel plans or something else that's personally relevant.

You don't need an hour-long vocabulary session every day. Consistency matters more than having a complicated study system.

What if I understand English but still can't find the words?

This is a very common stage of language learning.

You may understand articles, follow YouTube videos and recognise hundreds of words — but speaking can still feel surprisingly difficult.

That's because understanding a word and producing it are different skills.

If this is happening to you, spend more time on active English:

• speak about familiar topics
• retell something you've read or watched
• write short texts using new vocabulary
• answer questions without preparing your response
• practise conversations with another person
• deliberately use recently learned expressions

A teacher can also help here because you get immediate feedback and opportunities to use vocabulary in context.

If you'd like more personalised speaking and vocabulary practice, you can find an English teacher on Langu and choose someone whose experience and teaching style match your goals.

Why do I keep forgetting English words? The short answer

Forgetting vocabulary doesn't necessarily mean you're bad at languages.

You may simply be recognising too much and actively recalling too little, learning words without enough context, or not using them often enough.

Instead of trying to memorise more and more vocabulary, try changing how you practise it:

1. Choose fewer, more useful words.
2. Learn them in context.
3. Test yourself with active recall.
4. Review them over time.
5. Say them out loud.
6. Keep track of words you repeatedly forget.
7. Use new vocabulary in real conversations.

And remember: forgetting a word isn't the opposite of learning it. Sometimes forgetting and retrieving it again is exactly what helps it stick.
