Questions & Answers about Kerro minulle totuus.
Kerro is the second-person singular imperative of kertoa. In plain terms, it is the form you use when telling one person to do something.
So:
- kertoa = to tell
- kerro! = tell!
In this sentence, kerro means tell as a command or strong request.
Finnish usually does not need subject pronouns when the verb form already shows the person. With imperatives, this is especially normal.
So Kerro minulle totuus already means Tell me the truth without needing sinä.
If you added sinä, it would sound marked or emphatic rather than neutral.
