Klassifitseerisin

Klassifitseerisin is an Estonian verb form that means “I classified.” It is the first-person singular simple past tense of the verb klassifitseerima, which means to classify. The word is built from the stem klassifitseer- and the infinitive ending -ima, with the standard Estonian past-tense marker indicating that the action was completed in the past. This form is used in narratives or explanations where the speaker reports having sorted or grouped items, data, or observations.

In usage, klassifitseerisin appears in contexts such as data analysis, research, library and information sciences, or any situation involving categorization. It is an active voice construction and contrasts with the present tense klassitseerin (I classify) and the third-person past form klassifitseeris (he/she classified). The related nouns and verbs—klassifikatsioon (classification) and klassifitseerida (to classify)—share the same semantic field, making klassifitseerisin part of a broader family of words around classification in Estonian.

Examples of use include statements like: Ma klassifitseerisin need dokumendid kahte kategooriasse. or Ma klassifitseerisin need andmed vastavalt nende omadustele. These illustrate how the form anchors an action in the speaker’s past and ties the action to a concrete outcome, such as categorization into groups.
