varies

Varies is the third-person singular present tense form of the verb vary. To vary means to differ in some respect or to change within a range or set of conditions. When something varies, it does not remain fixed and can show differences across people, places, times, or circumstances.

Common usages include: "Prices vary by region," "Results vary from study to study," and "Climate varies with elevation." The word vary is often followed by prepositions such as by, among, or in, and by phrases like "vary from... to..." The accompanying adverbial phrases indicate range or distribution.

Originating from the Old French varier and the Latin varius, the term carries a sense of changeability or diversity. Related forms include vary (the base form), variation, various, variety, variable, and variability; the noun form is variation.

Notes: varies denotes ongoing or habitual difference rather than a single fixed value. In statistical contexts, variability describes how data points differ from a central tendency. The term should not be confused with various, which means "many different."
