How to Use the 'Interleaving' Technique to Master English Irregular Verbs Faster

You sit down to study irregular verbs. You write “go–went–gone” ten times. It feels productive.

Next day, you see “go” again, but your brain draws a blank.

That’s not your fault. That’s how most people study wrong.

The problem isn’t your memory — it’s your method. You’re blocking practice by group, which makes you feel confident now but forget quickly later. There’s a better way, and it’s called interleaving.

What Is Interleaving, and Why Does It Work for Verbs?

Interleaving means mixing different tasks or topics in a single study session. Instead of drilling one type of irregular verb for 20 minutes, you jump between different patterns.

For example, instead of studying only “sing–sang–sung” verbs today, you mix in “buy–bought–bought” and “write–wrote–written” right away. Your brain has to work harder to retrieve the correct form — and that extra effort is what makes it stick.

Psychologists call this the desirable difficulty principle. Easy practice feels good but builds weak memory. Hard retrieval builds strong, lasting recall.

The Usual Way: Blocked Practice (And Why It Fails)

Most learners group verbs by pattern:

• Group A: sing – sang – sung
• Group B: ring – rang – rung
• Group C: swim – swam – swum

You look at that list and think, I’ve got this. But the truth is, you’re not really learning. You’re guess-picking based on pattern similarity, not on real recall. When you later hear “I ___ a song yesterday,” your brain has to choose from sing, sang, sung — and since you learned them together, it can’t pick the right one fast enough.

How to Apply Interleaving to Irregular Verbs: A 3-Step Plan

You don’t need fancy apps or expensive courses. Just change how you arrange your practice.

Step 1: Break the Verb Tables

Grab a list of 12–15 common irregular verbs. Don’t sort them by pattern. Write them in random order, like this:

• go – went – gone
• buy – bought – bought
• swim – swam – swum
• write – wrote – written
• teach – taught – taught

Mix them up completely. Use verbs from different groups: ones that change the vowel, ones that end in -t or -ght, and ones that don’t change at all.

Step 2: Use a Random Test Format

Create a simple self-test. Give yourself the base form and a blank for the past tense. Keep shuffling the order each time.

go → ? → ? buy → ? → ? swim → ? → ?

Cover the answers. Say the missing forms aloud. Uncover after 3 seconds to check.

Don’t just read — say the answers out loud. Speaking forces your brain to retrieve the form faster.

Step 3: Mix Verb Practice with Real Sentences

Irregular verbs only matter if you can use them naturally in conversation. After each random test, write two sentences with verbs you got wrong.

Example:

• Yesterday, I swam in the lake.
• She has written three emails this morning.

This bridges the gap between “knowing the form” and “using it without thinking.”

Why Interleaving Beats Repetition for Long-Term Retention

Blocked practice works on short-term memory. You can pass a quiz tomorrow if you repeat 10 verbs today. But what about next week? Next month?

A famous study by Rohrer and Taylor (2007) compared blocked practice with interleaving in math. Students who interleaved performed much worse during practice — they felt confused and frustrated. But on a delayed test one week later, the interleaving group scored 43% higher.

The same principle applies to language. The feeling of confusion during interleaved practice is a sign that your brain is actually building long-term connections. Don’t let discomfort trick you into going back to blocked lists.

A Quick Reference: Which Patterns to Mix

Mix at least two different patterns every session. Don’t spend more than 10 minutes on verbs per day — interleaving works best in short, frequent bursts.

You’ve learned the theory. Now check how well you actually remember irregular verbs in a real test environment.

English Measure offers free Reading, Listening, Writing, and Speaking tests that use natural verb forms in context. You’ll see immediately which irregular verbs still trip you up — and you can apply interleaving to fix exactly those gaps.
