Questions & Answers about Äidinkieleni on suomi, mutta vastaan sinulle italiaksi.
Why do we use the -ksi ending on italiaksi here?
The translative case (ending in -ksi) is used to express the language in which something is spoken, written, or communicated. While English uses the preposition "in" ("in Italian"), Finnish attaches the -ksi suffix directly to the language name.
If we say italiaksi for "in Italian", why is Finnish just suomi and not suomeksi?
It depends on the word's role in the sentence. In the first half, Finnish is the noun itself describing your mother tongue ("My mother tongue is Finnish"), so it stays in the basic nominative case: suomi. In the second half, Italian is the medium of communication ("I answer in Italian"), which requires the translative -ksi.
Why do we use sinulle instead of just sinä or sinua?
The verb vastata (to answer) requires the allative case (the -lle ending) for the person receiving the answer. You can think of it as literally saying "I answer to you".
How is the word äidinkieleni put together?
It's a compound word consisting of äidin (mother's, which is the genitive form of äiti) and kieli (tongue/language), topped off with the possessive suffix -ni (my). Notice the consonant gradation where the t in äiti weakens to a d in äidin.
Why are suomi and italia written with lowercase letters?
Unlike English, Finnish never capitalizes the names of languages, nationalities, or days of the week unless they happen to be the very first word of a sentence.
