kasutasid

Kasutasid is an Estonian verb form belonging to the verb kasutama, meaning to use. It represents a past tense form and is used with certain subjects to indicate that an action of using something happened in the past. The form can appear with both the second person singular and the third person plural, depending on the subject of the sentence. For example, kasutasid sa seda midagi or nad kasutasid neid vahendeid.

In Estonian grammar, kasutasid is part of the regular past tense paradigm for verbs whose infinitive ends in -da or -ta, such as kasutama. The past tense endings attach to the verb stem kasut- and reflect person and number. The more explicit second-person plural past form is kasutasite, which distinguishes you (plural) from you (singular).

Common usage notes: kasutasid is widely used in spoken and written Estonian to describe past usage of an object, tool, method, or resource. It often appears in narratives, reports, and everyday conversation when recounting how something was used previously. Like other past tense forms, it relies on context or explicit subject pronouns to clarify who performed the action.

Etymology and related forms: kasutama is the verb from which kasutasid derives. Related nouns include kasutus (use, utilization) and kasutamine (utilization). A closely related Finnish cognate is käyttämään, reflecting common Finno-Ugric roots for the concept of using.
