Questions & Answers about Minusta tämä vastaus on rehellinen.

What exactly does minusta mean here, and why isn’t it just minä?

Minusta is the elative case (-sta/-stä) of minä (I). Literally it means from me, but in expressions of opinion it is idiomatic and means in my opinion / I think.

So:

• minä = I (nominative)
• minusta = from me → in this usage: I think / in my opinion

This is a very common pattern in Finnish: using a locative case form of a person pronoun to express mental states or opinions:

• Minusta tämä on hyvä. – I think this is good.
• Sinusta tämä on tylsää. – You think this is boring.

In your sentence, minusta does not mean physical movement but introduces your opinion.

Is minusta the subject of the sentence?

No. The subject is tämä vastaus (this answer).

Breakdown:

• Minusta – adverbial phrase expressing whose opinion it is (in my opinion).
• tämä vastaus – subject (this answer).
• on – verb to be, 3rd person singular, agreeing with tämä vastaus.
• rehellinen – predicate adjective describing tämä vastaus.

So structurally, the sentence is like:

• In my opinion, this answer is honest.

Minusta is not the grammatical subject; it’s more like an adverbial of viewpoint.

Why is it minusta and not minun mielestäni? Are minusta and minun mielestäni the same?
