What does really mean?
Really is an English adverb with several closely related uses. Most commonly, it emphasizes a quality or feeling, as in “really difficult” or “I really enjoyed it.” It can also indicate that something is genuine or true, meaning “indeed” or “in fact”: “She really was the best candidate.” When used by itself, as in “Really?”, it expresses surprise, disbelief, or a request for confirmation. The word is especially common in informal conversation, where it adds emotional emphasis without changing the basic meaning of a sentence. In more formal contexts, alternatives such as truly, genuinely, or indeed may sound more polished. Although pronunciation and usage are broadly similar in British and American English, the degree of emphasis can vary with tone and context. Its flexibility makes it useful both for expressing strong feelings and for affirming the reality or truth of something.

Where does really come from?
Really was formed in late Middle English by adding the adverbial suffix -ly to real, originally conveying the sense “in a real or genuine manner.” The adjective real comes through Anglo-French from Latin realis, derived from res, meaning “thing” or “matter.” The same Latin root later produced English words such as reality, realize, and realistic, while really developed especially in English as both an adverb of truth and an intensifier.
How really is actually used
In everyday speech, really is common as an intensifier and may sound informal or emotionally emphatic. In formal writing, truly or genuinely can be preferable. Its use as a standalone response often conveys surprise, disbelief, or genuine interest.
