Synonym discussion
Sense: noun/1
The noun 'ex' is the most casual and widely used term for a former romantic partner. Unlike 'former,' which is an adjective needing a noun ('my former wife'), 'ex' stands alone as a noun. 'Ex-partner' is slightly more formal and is often chosen when the relationship type is unclear or when the speaker wants to avoid specifying marriage versus dating. 'Old flame' carries a warm, nostalgic tone — it hints that the relationship ended long ago and the speaker looks back on it without bitterness. Compare: 'I saw my ex at the station' (neutral, everyday) versus 'I ran into an old flame from university' (wistful, distant past).

Etymology
The noun 'ex' (plural 'exes') comes from the prefix 'ex-', which itself traces back to Latin 'ex' meaning 'out of' or 'from.' By the early 1800s, English speakers began dropping the second part of compounds like 'ex-wife' and 'ex-husband,' using 'ex' alone as a noun to mean a former spouse or partner. The preposition 'ex' (as in 'ex warehouse') was borrowed directly from Latin and has been used in English legal and commercial writing since the 1600s. The abbreviation 'ex.' for 'example' developed from the first two letters of the word.
