Ühtaegu

ühtaegu is an Estonian adverb meaning "at the same time" or "simultaneously." It is used to indicate that two or more actions or events occur concurrently or that one action happens in parallel with another. The word is recognized in standard Estonian and is used in literary, academic, and formal writing; in contemporary everyday speech it is relatively less common than colloquial equivalents.

Etymology and cognates: ühtaegu derives from Finnic language roots that express simultaneity or togetherness. It is closely related to Finnish yhtää aikaa and to other Estonian forms that convey timing or sameness. The form is a single word with the adverbial sense, and it can modify verbs or clauses to set a temporal frame for the described events.

Usage notes: ühtaegu appears in contexts describing concurrent actions, parallel processes, or joint developments. It is found in formal prose, poetry, and historical texts, where precision of timing is important. In translation, it is typically rendered as "at the same time" or "simultaneously." In everyday Estonian, simpler expressions such as samal ajal are more common, but ühtaegu remains a recognized literary and precise option.
