Questions & Answers about kaigishitsu de kaigi o shimasu.

Why is で used after 会議室 instead of に?

In Japanese, で marks the location where an action takes place. Here, 会議をします (“hold a meeting”) is the action, so you say 会議室で.

• 会議室で会議をします = “We hold a meeting in the meeting room.”
  By contrast, に marks a destination or point of arrival:
• 会議室に行きます = “I go to the meeting room.”

Why do we need を after 会議? Could we omit it?

を is the direct‐object marker, and 会議 is what you’re “doing” with する.

• 会議をする = “to hold a meeting.”
  In casual speech you might hear 会議します (omitting を), but in formal or clear writing it’s standard to include を to avoid ambiguity.

Why does 会議 appear twice—in 会議室 and again as the object?

They’re actually two separate words, just sharing the same kanji:

• 会議室 (会議 + 室) = “meeting + room” = meeting room.
• 会議をする = “to hold a meeting.”
  So one is a compound noun naming the room, and the other is the noun you “do.”

Could I say 会議室で会議があります instead of ?
