illustreerivad

Illustreerivad is the third-person plural present tense form of the Estonian verb illustreerima, meaning to illustrate or to provide illustrations. It denotes that multiple subjects are performing the action of illustrating in the present.

As a finite verb form, illustreerivad is used with a direct object in constructions describing current actions. For example, Nad illustreerivad oma ettekannet diagrammidega. Here the subjects (they) illustrate their presentation with diagrams. The form is active voice and transitive, requiring a direct object that is being illustrated.

In addition to its finite use, illustreerivad can appear in the present active participle paradigm, functioning as a participial adjective when describing plural nouns. In this use, it conveys a meaning akin to illustrating or demonstrative, and it agrees with the noun in number. For instance, illustreerivad näited would translate roughly as “illustrative examples” or “examples that illustrate.” This participial usage is common in academic and technical writing to characterize examples, figures, or explanations.

Etymology and morphology: illustreerivad derives from the infinitive illustreerima, which is formed with the common Estonian verb suffix -ma and a root compatible with the stem illustreer-. The present tense and participial forms follow standard Estonian conjugation patterns for -ima verbs.

Overall, illustreerivad serves as a versatile word in Estonian, functioning as a finite verb form indicating current illustrating action by multiple subjects, and as a present active participle form used to describe illustrating-related characteristics of nouns.
