unusually

Unusually is an adverb describing something done in a manner that differs from what is typical or expected. It modifies verbs, adjectives, or other adverbs, signaling a deviation from the norm. In use, it often conveys that a characteristic or event stands out in comparison with what is typical in a given context.

Origin and formation: The adverb is formed from the adjective unusual by adding the suffix -ly. The adjective unusual derives from un- (a negating prefix) attached to usual, which comes from Old French and ultimately Latin relating to use or habit. The combination yields a standard English adverb used to describe how something occurs or appears.

Usage: In writing and speech, unusually is used to express exceptionality or surprise, but it can also soften statements by hedging. It is common in descriptive prose, reporting, and journalism. Alternatives include remarkably, notably, exceptionally, or simply notably, depending on the degree and tone intended.

Examples: The weather was unusually warm for October. The meeting proceeded unusually quickly. A crowd gathered unusually early for a weekday. These examples illustrate how unusually introduces a departure from what is typical in a given situation.
