täysikuulla

Täysikuulla is a Finnish adverbial phrase meaning “on the full moon” or “under a full moon.” It is formed from the word täysikuu (the full moon) plus the adessive suffix -lla, which marks a location or a temporal reference in Finnish.

In language use, täysikuulla is primarily found in literary, poetic, or descriptive contexts. It is used to evoke moonlight, atmosphere, and nocturnal imagery, rather than to convey a factual astronomical statement. In everyday speech, speakers may opt for more straightforward expressions about the moon phase, but täysikuulla appears when a stylistic or atmospheric effect is desired.

Etymology and grammar: Täysikuu provides the base noun meaning “full moon,” and the suffix -lla functions as the adessive, yielding a phrase that situates an action or scene at the time of and under the conditions of the full moon. As a fixed expression, its primary function is to set a temporal or atmospheric frame within a sentence.

Cultural notes: The full moon features prominently in Finnish folklore and contemporary storytelling, often linked to themes of transformation, mystery, or heightened emotion. Täysikuulla serves as a concise linguistic marker that anchors such imagery in a natural and culturally familiar phrase.
