trenutku

Trenutku is a grammatical form of the noun trenutak, used in several South Slavic languages to denote a moment or instant in time. In Croatian, Serbian and Bosnian, trenutak is masculine, and trenutku appears as the dative singular and the locative singular. This form is most often found after prepositions that indicate location in time, for example u trenutku (at the moment) or na trenutku (at the moment).

In usage, trenutku functions as a temporal noun within phrases that point to a specific point in time, and it can appear in both written and spoken language, including journalism, fiction, and academic prose. The meaning remains close across contexts: a particular moment rather than a prolonged period.

In Slovenian, a closely related term is trenutek, with the locative singular also taking a form similar to trenutku depending on the preposition used. The general sense—referring to a precise point in time—aligns with its South Slavic counterparts, though the exact inflection and prepositional combinations vary by language.

Etymology is generally traced to a common Slavic root associated with time or moment, with trenutku serving as a case form rather than a separate lexical item. See also trenutak (the base noun in many South Slavic languages) and its Slovenian equivalent trenutek for parallel usage.
