timeadverbial

Timeadverbial (often written as two words in description, though typically seen as time adverbial in practice) refers to an expression that provides information about when an event occurs and functions as an adverbial of time. They include single-word adverbs (yesterday, now, soon), prepositional phrases indicating time (in the morning, last week, during the summer), and temporal clauses (when I arrived, after the meeting ended). Time adverbials answer questions about timing, such as when an action took place, and can anchor the proposition to the reference time of the utterance. They may be deictic, relying on the time of speech (today, tomorrow), or non-deictic, anchored to another time point (two years ago, next month).

The primary role of time adverbials is to establish temporal context, indicate sequencing, and aid cohesion in discourse. They can modify the verb directly (He arrived yesterday) or modify the entire clause (Yesterday, we changed the plan). English tends to allow flexible placement: sentence-initial fronting for emphasis (Yesterday, I saw him), mid-position after the subject, or sentence-final after the predicate. They can also appear as part of temporal adverbial clauses to indicate a time relation (When I finished, I left).

Cross-linguistic variation is common. Some languages permit a wide range of placements for time adverbials, while others constrain them more tightly. Despite such variation, time adverbials consistently contribute to the temporal interpretation of events and help readers and listeners situate actions in time.
