Upildomas

Upildomas is a Lithuanian grammatical term describing the present passive participle form of a verb meaning to fill up. It is used to indicate that a subject is in the process of being filled or is prepared to be filled. The form is most commonly encountered in technical or descriptive contexts, and can function both predicatively and attributively.

Morphology and forms: Upildomas is the masculine singular nominative form. Lithuanian present passive participles follow gender and number agreement, producing upildoma (feminine singular), upildomi (masculine plural), and upildomos (feminine and/or plural). The stem combines the root pild- with a prefix that conveys the sense of completion or filling, and the suffix -omas marks the present passive participle.

Usage: In sentences, upildomas often describes containers, spaces, or systems that are being filled. For example, talpykla yra upildoma vandeniu means “the reservoir is being filled with water.” As an attributive modifier, it may appear as upildomas rezervuaras, meaning “a reservoir that is being filled.” In many contexts, synonymous forms such as uzpildomas or pildomas are used as well; upildomas emphasizes the ongoing process or imminent completion.

Etymology and relation to other terms: The form derives from the verb pildyti or upildyti, with a prefix that signals filling. Related terms include pildymas (the act of filling) and uzpildymas (the act of filling up to capacity). Upildomas is primarily found in descriptive, procedural, or technical Lithuanian rather than everyday speech.

Notes: While legitimate in grammar, upildomas is less common in casual language and may be encountered mainly in manuals, specifications, or linguistic descriptions.
