tulehtuu

Tulehtuu is the present tense, third-person singular form of the Finnish verb tulehtua, meaning to become inflamed or to develop inflammation. It is used to describe a change in a body tissue or organ from a healthy state to an inflamed state, such as skin, mucous membranes, or internal organs.

In medical and everyday language, tulehtua describes inflammation caused by infection, irritation, allergy, injury, or autoimmune responses. Common usage includes statements like haava tulehtuu (the wound becomes inflamed) or kurkku tulehtuu (the throat becomes inflamed). The form tulehtuu can thus appear in sentences referring to any subject that undergoes the process of inflammation.

Tulehtua is related to several Finnish terms. Tulehdus is the noun for inflammation, and tulehtuminen refers to the process or state of inflaming. These related words are frequently used in medical contexts as well as in general descriptions of bodily health and illness. The verb is intransitive, focusing on the state change itself rather than an active agent causing the inflammation.

Etymology traces the word to roots connected with inflammation, with tulehdus as the common noun for the condition. In clinical writing, tulehtua and its forms are standard for describing the onset or progression of inflammatory processes in tissues and organs.
