paksuuntuu

Paksuuntuu is a Finnish intransitive verb meaning “it thickens” or “it becomes thicker/denser.” It is formed from the adjective paksu, meaning thick, with the inchoative suffix -untua, which indicates a change of state. The word is used when a substance or phenomenon increases in viscosity or density, or when a situation becomes more burdensome or complex in a figurative sense.

Common contexts for paksuuntuu include cooking, weather, and physics or everyday descriptions. For example, a sauce or emulsion thickens as it simmers, fog or smoke thickens as temperatures drop or conditions change, and a narrative or situation can thicken, sometimes in a metaphorical sense such as “the plot thickens.” The verb can thus cover both tangible changes in physical properties and more abstract accumulations or complications.

Grammatically, paksuuntuu is used as an intransitive verb; the subject of the sentence is the thing that thickens, and no direct object is involved. The present tense form paksuuntuu is used for third-person singular subjects, while other conjugations follow standard Finnish verb conjugation patterns for the -ua/-untua class.

Etymologically, paksuuntuu derives from the root paksu and the word-forming suffix -untua, which creates verbs of becoming or changing state. Related terms include paksu (thick) and tiheä (dense), with tiheentyä as a close synonym in some contexts. The concept can be extended metaphorically to describe processes or plans that become more substantial or complex over time.
