mostly

Mostly is an adverb used to indicate that something is true for the majority of cases or to a large extent, but not completely. It derives from most plus the suffix -ly, forming a modifier that can qualify verbs, adjectives, or other adverbs. In meaning, mostly signals predominance or a general tendency rather than totality.

Usage and nuance: It can modify a wide range of expressions, as in “The team mostly won the game,” “The weather was mostly sunny,” or “The audience was mostly students.” It often conveys an approximate or hedged claim and is common in both spoken and written English. It is less precise than words like mainly or largely, and less absolute than almost or nearly: “mostly finished” implies some parts remain incomplete, whereas “almost finished” stresses near completion.

Comparison with related terms: mostly emphasizes what is typical across cases, while mainly points to the principal part or purpose. By and large indicates broad, often qualitative assessment. In everyday speech, mostly can soften statements and make them less sweeping.

Stylistic notes: In weather forecasts and media, “mostly sunny” or “mostly cloudy” describe conditions with occasional variations. In data reporting, “mostly” indicates a majority but is not a strict statistic. Although common, “mostly” is less exact than a precise percentage or count, so writers choose it when accuracy and nuance are desired.
