Teetkö

Teetkö is a Finnish grammatical form used to form a question. It is the second person singular present indicative of the verb tehdä, meaning "to do" or "to make," combined with the question particle -kö. The result teetkö literally means “are you making/do you make …?” and is used to ask someone about what they are doing or making.

Formation and spelling are straightforward: teet is the second person singular present form of tehdä, and the question particle -kö attaches to it to create a yes‑no question. The ending follows Finnish vowel harmony, so the particle appears as -kö after front vowels such as e. Thus teetkö is the standard spelling, as in Teetkö kahvia? (Are you making coffee?)

Usage and examples illustrate its role in everyday Finnish. It is commonly used with an object, for example: Teetkö kahvia? (Are you making coffee?), Teetkö ruokaa? (Are you cooking/preparing food?), Teetkö tämän? (Are you doing this?). The form is typical in spoken language and in informal written dialogue.

Variants and related forms include teet (you make) for the plain present tense, and teettekö for second person plural (you all make) in questions. The construction of teetkö is part of a broader pattern in Finnish where the question particle -ko/-kö attaches to the word it follows, with the form adapting to vowel harmony.

Overall, teetkö is a common and productive way to ask someone about activities or actions in the second person singular, and it demonstrates the standard Finnish mechanism for forming yes–no questions.
