Questions & Answers about Isi on keittiössä.

How would we change this sentence to say "His dad is in the kitchen" using the grammar from this lesson?
You would need the genitive pronoun hänen (his/her) and the third-person possessive suffix -nsä. If we use the standard word for father (isä), the sentence becomes Hänen isänsä on keittiössä.
Why is the word isi used here instead of isä?
Isi is a casual, affectionate word for "dad" or "daddy", commonly used by children or when speaking within a family. Isä is the standard, more neutral word for "father".
If I wanted to say "his daddy", can I add the possessive suffix to the informal word isi?
Yes, possessive rules still apply to informal words! You include the pronoun hänen and attach the suffix -nsä directly to the word, making it hänen isinsä.
I know the ending -ssä means "in" or "inside". Why does keittiö take -ssä instead of -ssa?
This is a quick reminder of vowel harmony. The root word keittiö (kitchen) contains the front vowel ö (as well as the neutral vowels e and i). Because there are no back vowels (a, o, u), it must take the front-vowel version of the ending, which is -ssä.
