Business Vocabulary｜会議・メール・交渉で“出る”語彙

ビジネス英語は、難しい単語よりいつも同じ型が強い。ここは“出る語彙”をチャンク（まとまり）で固定するページ。

コア概念は5つだけ： Decision / Priority / Risk / Timeline / Ownership（担当）
この5つが拾えれば、会議もメールも回る。

会議の核チャンク（最優先）

目的チャンク（そのまま使う）
開始Let’s get started. / The goal today is ___. / We have 30 minutes.
整理Let me summarize. / Just to confirm, ___. / Are we aligned on ___?
決定So the decision is ___. / Let’s go with ___. / We’ll proceed with ___.
担当Who owns this? / Can you take this? / Let’s assign an owner.
期限What’s the due date? / Can we commit to Friday? / Let’s set a deadline.

進捗・ブロッカー語彙

  • on track / behind schedule / ahead of schedule
  • blocked / stuck / waiting on ___
  • dependency / constraint / assumption
  • risk / issue / mitigation
  • ETA / timeline / milestone
日本語の「課題」は英語で分解：risk（起きるかも）/ issue（もう起きた）/ blocker（進まない理由）。

“強い依頼”の型（丁寧・速い）

  • Could you ___ by EOD?
  • Can you send me ___ by tomorrow?
  • Please confirm ___ by Friday.
  • If possible, could you prioritize ___?
ポイント：依頼＋期限＋成果物。

メール語彙（Subjectも含む）

Subjectの型
  • Action required: ___
  • Follow-up: ___
  • Decision needed: ___
  • Status update: ___
本文の型
  • Thanks for your time today.
  • As discussed, ___.

曖昧を潰す語彙
  • specifically / in detail / at a high level
  • for now / going forward / as of today
  • at minimum / ideally / if needed
  • scope / deliverable / acceptance criteria
英語は“線を引く”言語。曖昧を残すと事故る。

交渉の核語彙（trade-offの言語）

  • constraint / flexibility / non-negotiable
  • trade-off / in exchange for / on the condition that
  • meet halfway / revised proposal / counteroffer
  • terms / pricing / payment schedule
  • commit / guarantee / best effort
交渉は単語より“構造”：constraint → trade → summary。

実戦ミニセット（これだけ暗記）

  1. Let me summarize what I heard…
  2. Just to confirm, the decision is ___, correct?
  3. Who owns the next step?
  4. What’s the due date?
  5. If we do A, can you commit to B?
  6. That won’t work for us because ___.
  7. I’ll send a quick recap in email.
語彙というより“武器”。これで会議の主導権が取れる。
