300 English Idioms Flashcards for Work and Daily Life

You do not really know an idiom until you know where it fits.

Literal words do not help much when someone says you need to get on the same page, keeps a comment off the record, or feels between a rock and a hard place. The real mistake is often not the meaning but the situation: an idiom can be understood and still sound wrong in a meeting, a negotiation, or a tense conversation with a friend. This deck gives you 300 English idioms as whole units, each on its own card. The cards are split into work-and-business (55), people-and-relationships (50), emotion-and-reaction (45), difficulty-and-risk (50), time-and-money (45), and speech-and-opinion (55). On the back you get Meaning, Nuance, and Example, so you learn the sense, the register, and a natural sentence together. Once the cards are on a spaced-repetition schedule, the idioms you can answer stop coming back for a while and the ones you cannot keep returning until they stick. The deck chooses coverage over long explanations: you get the phrase, when it fits, and how it sounds in use, not origin stories or grammar lectures.

Frequently asked

Does this deck focus only on office idioms?

No. work-and-business has 55 cards, but the deck also covers people-and-relationships (50), emotion-and-reaction (45), difficulty-and-risk (50), time-and-money (45), and speech-and-opinion (55).

What does the Nuance field actually tell me?

It shows the register and social fit of the idiom. For example, 'on the same page' is common informal business English, while 'off the record' marks a boundary around sensitive remarks.

Why doesn't this deck include origin notes or long grammar explanations?

Because the point here is fast recognition and usable recall. Each card keeps the focus on meaning, situation, and a natural sentence, so study time goes into choosing the phrase well.

Can I import the whole deck on the free plan?

Yes. Importing a saved deck runs no new AI generation and does not use your AI allowance, so the free plan imports all 300 cards. You can study, edit and delete them afterwards.

Will importing it twice create duplicates?

No. Cards you already have are skipped and only cards added in a revision come through. Including re-imports after deleting it, one official deck can be imported three times per account.

Can I use it on the web and in the mobile app?

Yes. The deck is added to your account rather than to a device, so the same cards and the same progress are there on the web, on iOS and on Android.

Can I edit the cards after importing?

Yes. Imported cards are yours: you can edit both sides, delete cards you do not need, change tags, and move cards to another deck.
