Conditional form of the verb

In English conditional is formed with the helping verb would (or sometimes could / should). Finnish language has it's own ending -isi for conditional. The ending is added between the stem and the personal ending as follows:

stem conditional ending personal ending other optional suffixes
kysy isi n
would I ask

Positive conditional

conditional conjugation, positive
Present singular Present plural
minä kysyisin I would ask me kysyisimme we would ask
sinä kysyisit You would ask te kysyisitte you would ask
hän kysyisi He/She would ask he kysyisivät they would ask

The stem is quite regular:

Negative conditional

The idea in negative conditional is the same as in "normal" negative sentence: you use the negative verb (en, et, ei...) and the main verb without the personal enging, but with the conditional ending -isi.

conditional conjugation, negative

minä en kysyisi I wouldn't ask me emme kysyisi we wouldn't ask
sinä et kysyisi You wouldn't ask te ette kysyisi you wouldn't ask

When to use conditional?

Most typically conditinals are used in if-statements. Note, that in Finnish the verbs in both phrases are in contitional (unlike in English).

Matkustaisin maailman ympäri, jos voittaisin lotossa.
I would traval around the world, if I won in the lottery.

Conditional is also used when you want to be polite:

Sulkisitko ikkunan.
Would you close the window, please.
Voisitko auttaa vähän?
Could you help me a little?
