Questions & Answers about Kova tuuli jatkui koko yön.
How is the past tense verb jatkui formed from its dictionary form?
The dictionary form is jatkua (to continue). Because it is a Type 1 verb, we drop the final -a to get the stem jatku-. To make it past tense, we add the past marker -i. For verbs whose stem ends in u, the u and i simply sit next to each other, giving us the "it" form jatkui.
Wait, isn't tuuli also a past tense verb meaning "blew"?
Yes! The word tuuli is a homonym: it can be either the noun for "wind" or the past tense of the verb tuulla (to blow). In this sentence, because we already have the main verb jatkui (continued), we know tuuli must be the noun.
Why does yö (night) end in -n in this sentence?
When you state the duration of an action (how long something happens), the time word takes the -n ending (the accusative case). The word koko (whole or all) is a special word that never changes its form, but the noun following it still gets the -n, so "all night" becomes koko yön.
Why use kova for a "strong" wind instead of vahva?
