Questions & Answers about Ikkunasta tulee vetoa.
Because -sta / -stä is the elative case, which often means out of or from.
- ikkuna = window
- ikkunasta = from the window / out of the window
In this sentence, it means the draft is coming from the window area, or more naturally, through the window. Finnish often uses a from case where English would say through.
Tulee is the 3rd person singular of tulla, meaning to come.
So literally, the sentence is something like:
- From the window comes draft
That sounds odd in English, but Finnish uses tulla in expressions like this quite naturally. It can describe something appearing, entering, or being felt from a source.
So even though English might say There is a draft coming from the window or A draft is coming in through the window, Finnish can say ikkunasta tulee vetoa.
