laulun

Laulun is the genitive singular form of the Finnish noun laulu, meaning "song." It is used to express possession or a close relationship between the song and another element, similar to the English construction "of the song." In everyday Finnish, laulun is attached to a head noun to form possessive phrases, for example laulun sanoitukset (the lyrics of the song), laulun kirjoittaja (the author of the song), or laulun kesto (the duration of the song).

Morphology and usage: The genitive singular is formed by adding -n to laulu. The corresponding genitive plural is laulujen. In addition to the genitive, Finnish offers other cases for laulu, such as illative lauluun (into the song) and inessive laulussa (in the song). Laulun typically appears as the modifier in a phrase indicating possession, association, or subject matter, with the head noun following or preceding depending on sentence structure. Examples include laulun sanoitukset, laulun säveltäjä, and laulun teemat.
