voiillisesti

Voiillisesti is a coined or hypothetical Finnish adverb used in linguistic discussions to denote an action performed with volition or ability. It is not part of standard Finnish and has no broad attestation in dictionaries or corpora.

Etymology and form: The form would be analyzed as an adverb built with the common suffix -isesti attached to a hypothetical stem derived from the verb voida, meaning “to be able (to).” While Finnish regularly forms adverbs with -isesti from adjectives or nouns, a native-form voiillisesti remains unattested and would be considered experimental or theoretical.

Meaning and usage: If encountered, voiillisesti would signal intentionality or voluntary effort rather than automatic or externally compelled action. It could appear in theoretical prose about argument structure or in speculative fiction. It is important to distinguish it from established equivalents such as omatoimisesti (“on one’s own initiative”) or other more conventional expressions for voluntariness.

Attestations and reception: Because it lacks broad usage, voiillisesti is typically described as a neologism or hypothetical form; readers should rely on explicit definition in the given text.
