totally

Totally is an adverb that means completely, entirely, or to a great extent. It derives from the adjective total, which in turn comes from the Latin totus meaning “whole” or “entire.” The suffix -ly marks it as an adverb and indicates its role as a degree modifier rather than a standalone lexical item.

It functions as an intensifier in informal English, modifying adjectives (totally different), verbs (totally changed), or whole clauses (We totally forgot). It can also function as an interjection in casual speech: Totally! to express strong agreement or enthusiasm.

Usage notes: In formal writing, alternatives such as completely, entirely, or utterly are often preferred. Some style guides view overuse of totally as casual or hyperbolic, though the word remains widely used in American English and in many other varieties. The emphasis conveyed by totally can shade meaning: it frequently signals certainty, enthusiasm, or emphasis rather than a precise degree of measurement.

Variants and related terms: Other common degree adverbs include absolutely, utterly, entirely, and completely. Totals of usage can vary by context and speaker, but it remains a common tool for conveying strong emphasis in informal discourse.
