What’s inside
Built to make it stick
400 idioms, 20 topics
Related idioms are learned together, topic by topic, rather than as a random list.
Your language’s equivalent
Where your language has a matching idiom you see it, marked as an exact or a close match — plus the literal meaning.
Spaced repetition
Lessons bring each idiom back on a schedule that fits how memory works.
Examples, grammar and audio
Five example sentences for every idiom, a short note on which words change, and pronunciation you can hear in different English accents.
Level and register
Each idiom is tagged with its CEFR level and whether it is informal, neutral or formal.
Reviews are never locked
Daily reviews of the idioms you have learned stay unlimited on Free too. What you have learned is always yours.
