What does egregious mean?
Egregious is an adjective describing something that is outstandingly bad — so glaringly wrong, offensive, or faulty that it stands out from ordinary failings. An egregious error is not a small slip but a shocking, conspicuous blunder; egregious misconduct implies conduct so far beyond acceptable bounds that it demands attention. The word is common in formal writing, journalism, and legal contexts, where it lends weight and severity to criticism. Interestingly, its history runs opposite to its modern sense: it comes from Latin egregius, meaning 'standing out from the flock' (from e-, 'out of', and grex, 'flock'), and was originally used in English as praise for someone remarkably good or distinguished. Over time the meaning reversed, and by the seventeenth century it had settled into ironic and then straightforwardly negative use. Today it is an emphatic, useful word for condemning faults that are not merely mistakes but flagrant ones.
Conspicuously and outrageously bad or reprehensible; glaringly wrong.
"The audit revealed egregious accounting irregularities spanning several years."
Almost exclusively negative in modern use; applied chiefly to abstract nouns such as error, failure, offence, or conduct.
(Archaic) Remarkably good; distinguished or eminent.
"He was accounted an egregious scholar throughout the university."
Egregious used to be a compliment: it meant 'standing out from the flock' in a good way, until English speakers turned it into one of language's great insults.

Etymology of egregious
Egregious derives from Latin egregius, literally 'standing out from the flock', formed from e- ('out of') and grex ('flock' or 'herd'), the same root that gives us gregarious, aggregate, and segregate. It entered English in the early sixteenth century with its original positive sense of 'remarkably good or distinguished'. By the early seventeenth century the sense had inverted — partly through ironic use — so that the word came to mean conspicuously bad, the meaning it has retained ever since. Its Latin relatives share the notion of gathering or standing apart from a group.

How egregious is actually used
Egregious is formal-to-neutral in register and almost always carries strong negative connotation today; it intensifies criticism rather than merely describing something bad. Its older positive sense ('distinguished') survives only in historical texts. It is typically applied to errors, offences, conduct, or failures rather than to people directly.
Easily confused with egregious
Gregarious means sociable and fond of company, while egregious means outstandingly bad — both derive from the same Latin root 'grex' (flock), but their meanings have diverged completely.
