suust

Suust is an Estonian word-form used in grammar rather than a standalone lexical item. It is the elative singular form of the noun suu, which means mouth. In Estonian, the elative case conveys origin or movement outward from something, and suust translates roughly as “from the mouth” or “out of the mouth.”

Morphology and usage

The form suust is created by attaching the elative suffix -st to the stem suu. As a grammatical case form, it appears in contexts where the source of speech, sound, or other emanations is being specified. In everyday language, suust tends to occur in phrases that describe something arising from or emitted by the mouth, such as spoken words or other oral expressions. It is a standard part of Estonian morphology and is used in both spoken and written varieties.

Etymology and relation to other forms

Suu is the base noun meaning mouth, and suust is its elative form. The elative case is one of several case endings in Estonian that mark relationships such as origin, source, and movement from within. Suust is related to other elative forms derived from different nouns, each following the general rule of adding -st to indicate source from that noun’s referent.
