Questions & Answers about Se on selvinny tosi hyvin.
Why does the word for managed end in -ny instead of -nyt?
This is a perfect example of spoken Finnish dropping word-final sounds. The standard written past participle is selvinnyt, but in everyday speech the final -t is almost always dropped, leaving just selvinny.
What tense is on selvinny, and what is its base verb?
This is the perfect tense, meaning has managed or has survived. The base verb is selvitä (a type 4 verb). In standard Finnish, you form this participle by replacing the -tä with -nnyt, which then shortens in spoken language.
Why is the pronoun se used if the English translation says He?
In spoken Finnish, se (literally it) is the most common way to say he or she in casual situations. The official human pronoun hän sounds quite formal and is mostly reserved for writing or very polite speech.
Is tosi also a colloquial feature in this sentence?
Yes! While the standard written word for really is todella, everyday spoken Finnish heavily favors using tosi (which literally means true) as a modifier before adjectives and adverbs.
