Questions & Answers about Eikö hänen leipomansa piirakka ole vielä valmis?
Why does leipomansa have the -nsa ending?
This is the agent participle form of leipoa (to bake). When the agent (the person doing the action) is a pronoun like hänen, the participle must take a matching possessive suffix. Here, -nsa matches the third-person pronoun hänen.
Could I just write hänen leipoma piirakka without the suffix?
In spoken Finnish, yes, it is very common to drop the possessive suffix. However, in standard written Finnish, whenever the agent is a pronoun (like minun, sinun, hänen), the possessive suffix on the participle is strictly required.
Why is the main verb ole instead of on?
Because this is a negative sentence. The sentence begins with Eikö, which is the negative verb ei combined with the question particle -kö. In a negative sentence, the main verb must be in its connegative form, which for olla (to be) is ole.
How does the grammar of hänen leipomansa piirakka work as a single block?
The agent participle (-ma or -mä) turns a verb into a word that describes a noun while also showing who performed the action. Here, hänen leipomansa acts just like an adjective describing piirakka (the pie).
