vaihesanaan
Vaihesanaan is a term used in linguistics to describe a word that can function as more than one part of speech depending on its context. This phenomenon, also known as conversion or zero derivation, is common in many languages, including English and Finnish. For example, in English, the word "run" can be a verb ("I run every day") or a noun ("I went for a run"). Similarly, in Finnish, words can shift their grammatical role without any change in their form.
The ability of a word to be a vaihesanaan is often dependent on semantic and syntactic cues
