Questions & Answers about ichijikan enchoushite, mochikomi ga dekiru koshitsu de moriagatta.

Why is 一時間 used here? Does it mean for one hour or by one hour?

Here 一時間 means by one hour / for an additional hour in the sense of extending the reservation.

So 一時間延長して means we extended it by one hour.

A learner might first think it means for one hour we got excited, but in this sentence 一時間 goes with 延長して, not with 盛り上がった.

What does 延長して do grammatically?

延長して is the て-form of 延長する, meaning to extend.

The て-form here connects actions:

• 一時間延長して = after extending it by one hour / and extending it by one hour
• 盛り上がった = we got lively / had a great time

So the sentence describes a sequence of events:

1. the time was extended,
2. then people had a great time in the room.

Depending on context, the て-form can sound like:

• and
• after doing
• by doing

Here and/after extending is the most natural reading.

Why is it 持ち込みができる instead of 持ち込める?
