How it worksConjugate

Verb forms on autopilot

Quick drills that turn verb endings into a reflex, so you stop stopping mid-sentence.

You type the right form of a verb for each person and tense, against a light timer.

Pick the right form

How to use it well

  1. Start with common verbs

    Be, have, go and want cover a lot of everyday speech.

  2. Keep sessions short

    Five minutes is plenty.

  3. Say the forms out loud

    Hearing yourself helps the forms come out faster when you speak.

Why it works

Practice turns rules into reflexes

Skill research shows that with practice, knowing a rule slowly turns into using it quickly and without effort.

Short regular drills beat long ones

Spreading practice over several short sessions leads to better long-term memory than one long session.

    Practice in a second language: Perspectives from applied linguistics and cognitive psychology

    Cambridge University Press

    What they did
    Brought together research on how practice changes language skills.
    What they found
    With repeated practice, a rule you know slowly becomes something you use quickly and with little effort.

    Distributed practice in verbal recall tasks: A review and quantitative synthesis

    Psychological Bulletin

    What they did
    Combined 317 experiments that compared spread-out practice with practice done all at once.
    What they found
    Spreading practice over time gave better long-term memory, and longer gaps helped more when the test was further away.

    The critical importance of retrieval for learning

    Science

    What they did
    Students learned 40 Swahili and English word pairs and kept either studying or testing each pair after they first knew it.
    What they found
    Repeated testing led to far better memory a week later. Extra studying added almost nothing.

The mistake most people make

Drilling verbs you never use

Do this instead

Practise the verbs from your own sentences first.
