You've probably used flashcards before. Word on one side, definition on the other. It works okay — until you realise you only remember the card, not the word.
That's where the cloze deletion technique comes in. It's a simple twist on traditional flashcards, but it makes a massive difference for mastering English grammar and vocabulary. Instead of a blank slate, you see a full sentence with one word or phrase removed. Your brain has to fill in the gap.
It's harder. That's exactly why it works.
What Makes Cloze Deletion Different
A normal flashcard asks: What does "ubiquitous" mean? You either know it or you don't. It's passive, binary.
A cloze deletion card looks like this:
"Smartphones have become ______ in modern life, found almost everywhere."
Now you're not just recalling a definition. You're placing the word in context, with grammatical clues (the verb tense, the adjective placement, the surrounding words). Your brain has to engage with the sentence structure, not just a vocabulary list.
This makes it a two-for-one technique. You're learning vocabulary and grammar simultaneously.
How to Build Your Own Cloze Cards
You don't need fancy software. A notebook works. But if you want to go digital, tools like Anki or Quizlet make it easy.
Here's a simple process:
Step 1 — Find a natural sentence. This is crucial. Don't invent weird sentences. Use ones you encounter while reading, listening to podcasts, or watching shows.
Step 2 — Identify the target word or structure. Maybe it's a collocation like "take into account" or a grammar point like the third conditional.
Step 3 — Remove that element and replace it with a blank. Keep enough context so the answer is clear, but not obvious.
Step 4 — Write the full answer on the back. That's it.
Let me show you the flow visually.

Grammar Gets Much Easier This Way
Abstract grammar rules are hard to remember. "Use the past perfect for an action that happened before another past action." That's dry.
A cloze card makes it concrete:
"When I arrived at the station, the train ________ (already / leave)."
The answer is "had already left". Every time you review this card, you're practising the past perfect in a realistic context. After a few reviews, it stops being a rule and starts being something you just feel is correct.
I've seen students who struggled with conditionals for years finally get them after a month of cloze practice. The technique forces you to produce the grammar, not just recognise it.
A Practical Example with Vocabulary
Let's say you want to learn the word "reluctant". Here's a bad card:
Q: What does "reluctant" mean?
A: Unwilling
Here's a good cloze card:
Q: "She was ________ to join the conversation, clearly uncomfortable."
A: Reluctant
The second card teaches you that "reluctant" is followed by "to" (reluctant to do something). You also learn the nuance — it's about hesitation, not refusal. That's the difference between knowing a word and being able to use it.
When to Use Cloze Deletion
This technique works best for:
- Collocations — "make a decision" (not "do a decision")
- Prepositions — "interested in," "depend on"
- Verb tenses — any time you mix up past simple and present perfect
- Phrasal verbs — context is everything with these
- Tricky vocabulary — words with multiple meanings
It's not great for learning massive lists of isolated words. Use traditional flashcards for that. Cloze deletion is for deeper, context-based learning.
One Quick Tip
Don't make your blanks too easy or too hard. If the sentence gives away the answer immediately, you're not learning anything. If it feels impossible, you'll get frustrated.
The sweet spot is a sentence where you can guess the answer with about 60% certainty — and the remaining 40% comes from thinking it through.
That's where real learning happens.
