Abruptly

Abruptly is an adverb describing an action or event that happens suddenly and without warning, often with little or no preparation. It denotes the manner in which something occurs or changes, and it commonly modifies verbs and entire clauses.

Etymology: The word derives from the adjective abrupt, which ultimately traces back to Latin abruptus meaning "broken off" or "steep". The English adverb arose by adding the -ly suffix to convey manner.

Usage notes: Abruptly commonly signals a sharp interruption or a rapid change in direction, tone, or circumstance. It is versatile in narrative and descriptive writing, but in formal prose more precise terms such as suddenly, unexpectedly, or quickly may be preferable to avoid harsh tone. Overuse can give sentences an abrupt or jarring feel.

Examples: The meeting ended abruptly when the fire alarm sounded. The car slowed and then stopped abruptly at the intersection. The announcement was made abruptly, catching many by surprise.
