Synonym discussion

Sense: adjective/1

'Outdated' is the everyday choice for things that no longer fit present life, such as software, rules, or facts in a textbook. 'Old-fashioned' can overlap, but it often points more to style, manners, or opinions, and it is sometimes warm rather than fully negative. 'Obsolete' is stronger and slightly more formal: it suggests a clear replacement, as when email made fax machines obsolete. 'Out-of-date' is very close to 'outdated' and is common in everyday speech, especially for information. 'Antiquated' is the harshest of these words and often sounds critical or even mocking. You might call a school website outdated, a view about family roles old-fashioned, and a cassette player obsolete.

Etymology

LatinOld FrenchEnglish

Built in English from the verb 'outdate', which joins 'out-' with 'date'. 'Date' came into English through French from Latin and first referred to the stated day or time of something. From the idea of belonging to an earlier date than the present one, 'outdated' came to describe ideas, tools, and information that no longer match current life.
