równoczesnego

Równoczesnego is the genitive singular form of the Polish adjective równoczesny, which means simultaneous or occurring at the same time. It is used to describe a noun in the genitive case that is masculine personal or neuter in gender, or to form noun phrases with determiners that require genitive. In general, równoczesnego agrees with the head noun in gender, number, and case.

Morphology and use: As a declined adjective, równoczesny has different endings depending on gender, number, and case. The form równoczesnego specifically appears in masculine personal and neuter nouns in the genitive singular. For feminine nouns in genitive singular, the corresponding form is równoczesnej. Examples include a phrase modifying a neuter noun in genitive like równoczesnego wystąpienia (simultaneous occurrence) or masculine personal contexts such as brak równoczesnego dopasowania (lack of simultaneous matching). The adjective is typically placed before the noun it modifies and inflects to match that noun.

Etymology and meaning: równoczesny derives from równy (equal) and czas (time), with the sense of matching in time or occurring at the same time. The form równoczesnego is part of standard Polish inflection and is used in formal, academic, and descriptive prose.

Usage notes: równoczesnego is distinct from równocześnie, which is an adverb meaning “simultaneously.” While równocześnie describes the manner of an action, równoczesnego functions as an attributive or predicative modifier within a genitive construction. It often appears in scientific, technical, or analytical writing when specifying the simultaneity of phenomena, events, or processes.
