Questions & Answers about Me emme riitelisi joka päivä.
Why is there a t in riitelisi when the dictionary form is riidellä?
This is a great example of consonant gradation! Riidellä (to argue) is a Type 3 verb. Type 3 verbs have the weak grade in their dictionary form (d) but take the strong grade (t) in the conditional mood, just like they do in the basic present tense (minä riitelen).
How exactly is the word riitelisi built from the strong stem?
To form the conditional, you start with the strong vowel stem of the verb. For riidellä, the stem is riitele-. When you add the conditional marker -isi, the final e of the stem is dropped because Finnish doesn't usually keep an e right before the conditional i. So, riitele- plus -isi becomes riitelisi.
Why doesn't riitelisi have a personal ending for "we", like -mme?
Because this is a negative sentence. In Finnish, the negative verb (emme) already shows who is doing the action. The main verb in a negative conditional sentence just takes the -isi marker without any personal ending. If it were a positive sentence, it would be me riitelisimme (we would argue).
Why is päivä in its basic nominative form here instead of the partitive?
