Questions & Answers about Minä tarvitsin uuden salasanan.
How do we get tarvitsin from the dictionary form tarvita?
Tarvita (to need) is a Type 5 verb. To form the past tense (imperfect), Type 5 verbs replace the final -ta or -tä of their dictionary form with -tsi-. This gives us the past stem tarvitsi-. Adding the personal ending -n for "I" makes it tarvitsin.
Why are the words for "a new password" in the genitive case (uuden salasanan)?
In Finnish, the object of a complete, affirmative action usually takes the genitive case ending -n to show that it is a total object. Because you needed a whole password, the noun takes this ending. Adjectives must match the noun they describe, so both uusi (new) and salasana (password) get the -n.
How does the word uusi (new) become uuden?
Many older Finnish words ending in -si have a stem that changes to -te- before adding endings. So, uusi becomes uute-. Then, because adding the -n ending closes the last syllable, consonant gradation happens: the strong -t- weakens to -d-, resulting in uuden.
