Hand writing notes while studying English
Why idioms are hard

The words make sense. The phrase doesn't.

An idiom is a phrase whose meaning can't be worked out from its words. Spill the beans has nothing to do with beans, and someone under the weather is simply feeling ill. Ordinary dictionaries explain each word separately, which is exactly why learners get idioms wrong.

SnapDic treats the phrase as one unit. Highlight it, and you get the meaning of the whole expression — not five separate definitions.

What every entry includes

  • A plain-English meaning written for learners

How to use it

Three ways to meet an idiom

Highlight it

Select two to four words — break the ice — and the meaning of the whole phrase appears.

Hover a word inside it

Hovering a single word gives that word's meaning, so you can compare.

Review it later

Every phrase you look up is listed in the SnapDic panel. SnapDic Plus saves them by day.

Tips for learners

Learning idioms that stick

  • Learn them in context. An idiom you met in a real article is far easier to remember than one from a list.
  • Notice the register. SnapDic tags informal phrases and slang — great in a chat, risky in an essay.
  • Collect related phrases. Spill the beans leads to let the cat out of the bag: two idioms for the price of one.
  • Watch phrasal verbs. Give up, give in and give out mean very different things. Highlight the whole verb to be sure.

Understand idioms the moment you see them

SnapDic for Mac is free. Also free for Chrome.
