Questions & Answers about Hän menee leipomoon, jossa on iso valikoima.
Why is the relative pronoun jossa used here instead of just joka?
The relative pronoun joka changes its case to match its role in the new clause. Because the large selection is in the bakery, the pronoun takes the inessive case (the "in" case), becoming jossa ("in which").
The word leipomoon uses the "into" case, but jossa uses the "in" case. Don't they need to match?
No, a relative pronoun gets its case from what it does in its own clause, not from the word it refers to. The person is going into the bakery (movement = leipomoon), but the selection is statically sitting inside the bakery (location = jossa).
The English translation says "which has", but isn't on the verb for "is"?
How do we form the illative ("into") case for leipomo?
For many words ending in a short vowel like leipomo, you form the illative case by doubling the final vowel and adding -n. This changes leipomo to leipomoon.
