Questions & Answers about sono ryokou wa sukkari dainashi ni natta.
Why is it その旅行 and not そのの旅行?
Because その is a determiner that directly modifies a noun, like that in English.
- その旅行 = that trip
- この本 = this book
- あの人 = that person over there
You do not use の after その / この / あの when they come before a noun.
By contrast:
- それ = that one
- その旅行 = that trip
So その must be followed by a noun, while それ can stand alone.
What does は do in this sentence?
は marks その旅行 as the topic of the sentence.
So the sentence is talking about that trip, and then saying what happened to it:
- その旅行は = as for that trip...
- すっかり台無しになった = it ended up completely ruined
In natural English we usually just say That trip was completely ruined, but Japanese often uses a topic-comment structure instead of matching English subject structure exactly.
Why is it なった and not だった?
