kirjut

Kirjut is the verbal stem appearing in forms and derivatives of the Estonian verb kirjutama, which means "to write." It is not the infinitive itself (the infinitive is kirjutama) but functions as a root used in conjugation, participles and word formation. Examples of derived words that reflect the same root include kirjutaja (writer) and kirjutamine (the act of writing).

Etymology traces the stem to Finno-Ugric word formation connected with the Estonian noun kiri ("letter") and Proto-Finnic *kirja- ("book, writing"), with the suffix -tama producing the verbal meaning "to cause or perform writing." The consonant and vowel alternations found around the stem are typical of Estonian verb morphology, which often uses multiple stems for different tense and mood forms.

In linguistic descriptions and language teaching, kirjutas a morpheme of interest for understanding regular and irregular patterns in Estonian verb conjugation and derivation. Outside of this grammatical role, "kirjut" is not commonly used as an independent lexical item in standard Estonian.
