Questions & Answers about Älkää roskatko käytävällä tai nurmikolla.
How do we form the negative command "älkää roskatko"?
This is the plural or formal negative imperative (a command given to multiple people or formally to one person). It starts with the negative verb älkää (do not). The main verb roskatko is formed by taking the affirmative plural command (roskatkaa) and changing the -kaa ending to -ko (or -kö depending on vowel harmony).
Which verb type is "roskata" (to litter), and how do we get the stem "roskat-"?
Roskata is a type 4 verb. To find the plural imperative stem for verbs ending in -ata/-ätä, you take the infinitive form and simply drop the final -a or -ä. This leaves the stem roskat-, to which you add the negative imperative ending -ko to get roskatko.
Why does the sentence use the "-llä" ending for "in the corridor" (käytävällä)?
The -lla/-llä ending (the adessive case) typically means "on" or "at". However, Finnish often uses it for open transit areas, yards, and public spaces where English would say "in". Because a corridor (käytävä) is a pathway or transit space, it takes -llä rather than the "in" ending (-ssä).
Why does "nurmikolla" only have one "k", if the basic word is "nurmikko" (lawn)?
It undergoes consonant gradation. The basic word nurmikko has a strong kk. Adding the -lla ending closes the final syllable (because it ends in a consonant and a vowel). This causes the strong kk to weaken into a single k, resulting in nurmikolla.
