extremely

Extremely is an adverb used to indicate a high degree of a property, condition, or action. It commonly modifies adjectives, participles, and other adverbs, as in extremely cold, extremely difficult, or extremely well. The use of extremely emphasizes intensity beyond a baseline level conveyed by the base word, and it can appear in both formal and informal contexts.

Origin and form: extremely derives from the adjective extreme, which traces back to Latin extremus via Old French extrême. The suffix -ly converts the adjective into the adverb form. Like other degree modifiers, extremely is flexible in position, typically placed before the word it modifies.

Usage considerations: In formal writing, extremely should be used sparingly to preserve impact. With absolute adjectives such as unique or perfect, many editors advise avoiding extremely because the combination can be perceived as excessive or redundant, though some contexts permit it for emphasis or rhetorical effect. In other cases, extremely can convey stronger emotion or urgency than very or highly.

Semantic range and nuance: extremely signals intensity, often without specifying a measurable amount. It is common in everyday speech, journalism, and advertising, but care is advised in scientific or precise documentation where qualifiers should reflect verifiable data. Synonyms include highly, exceptionally, or tremendously, each carrying slightly different connotations.
