このデッキについて

Ping me when it is ready works in a message to a colleague and reads badly in a letter to a client. Please do not hesitate to contact me is the reverse: correct in formal writing and stilted in a team chat. Learners who study business vocabulary as a flat list end up fluent and tonally wrong, which is a harder problem to notice than a missing word. This deck is 300 cards, one word or fixed expression per card, with the back giving the sense in plain English and, where it applies, a line on how formal it is and where it is used, whether that is email, a meeting, a report or speech only. The sections cover meetings and discussion, email and correspondence, projects and processes, finance and reporting, negotiation and clients, and people and organisation. General idioms with no workplace use are left out, and where a term is mainly British or mainly American the register line says so. Once the deck is on a spaced-repetition schedule, the expressions you use confidently stop coming back and the ones whose register you keep misjudging return until you stop misjudging them.

よくある質問

What is in each section of the deck?
Meetings and discussion has 50 cards, email and correspondence 55, projects and processes 50, finance and reporting 50, negotiation and clients 45, and people and organisation 50, for 300 in total. Every card carries section and subtopic tags, so you can drill only email phrases or only finance terms.
What level of English does it assume?
Roughly upper-intermediate. The definitions are in plain English and the examples are short, but the deck assumes you can already hold a conversation and are now working on the vocabulary a workplace uses. It is not a beginner course and does not teach general grammar.
Is it British or American English?
Both, with the difference marked. Where a term is used mainly on one side, such as the words for a bidding process or for redundancy, the register line names which variety it belongs to and gives the other one. Spelling follows British convention throughout.
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.
