Questions & Answers about Älkää unohtako tätä vaatimusta!
How is the noun vaatimus formed from a verb?
It comes from the verb vaatia (to demand, to require). It uses the suffix -mus, which is a very common variant of the -us/-ys and -os/-ös endings taught in this lesson. Adding this to the verb stem creates a noun representing the result of the action, so vaatimus means a requirement or a demand.
Why is the object tätä vaatimusta in the partitive case?
Because this is a negative sentence. In Finnish, if the verb is negative (like the negative command älkää used here), the object of that verb must almost always take the partitive case.
How does the negative imperative älkää unohtako work?
When telling a group of people not to do something, you use the plural negative word älkää. The main verb then takes the suffix -ko or -kö. For unohtaa (to forget), the stem is unohta-, making the plural command älkää unohtako.
Could I use älä unohda instead?
Yes, if you are addressing only one person informally! Älä unohda is the singular negative command, while älkää unohtako is the plural version used for two or more people (or in formal situations).
