Questions & Answers about Leipä loppui, joten ostan sitä huomenna lähikaupasta.
Because leipä is the subject of the verb loppui (to run out / to end). In Finnish, things that “run out” are usually expressed with the thing as the subject:
- Leipä loppui. = “Bread ran out.”
You’re not doing something to the bread; the bread is the thing that “ended,” so it appears in the nominative.
Loppui is the past tense (imperfect) of loppua. In this kind of sentence, loppua means to run out (or to be used up / to come to an end).
So loppui indicates that the running out happened already.
Because Finnish commonly uses the present tense to talk about a future plan when a time expression makes the future clear. Here huomenna (“tomorrow”) signals the future, so ostan naturally means “I will buy.”
You could also say aion ostaa (“I’m going to buy”) for extra explicit intention, but ostan huomenna is very normal.
