Synonym discussion
Sense: adjective/1
All five words can describe something that existed or happened before now, but they differ in scope and register. 'Former' is the most neutral and widely used in formal and informal contexts — it works for jobs, relationships, and statuses: 'a former teacher', 'a former champion'. 'Previous' emphasises order in a sequence and is especially common for immediately preceding items: 'her previous job' (the one right before the current one). 'Past' is broader and can describe a whole period: 'past presidents' may refer to everyone who has ever held the office. 'Ex-' is informal and restricted in register; it is standard for romantic partners ('ex-boyfriend') but sounds casual or dismissive with professional roles ('ex-boss'). 'One-time' is slightly more formal and highlights that the role was temporary: 'a one-time actor who now runs a restaurant'. In most professional contexts, 'former' is the safest and clearest choice.

Etymology
The word 'former' comes from Middle English 'former', which was originally a comparative form of 'forme' (first). 'Forme' itself comes from Old English 'forma' (first, foremost), which is related to 'fore' (before). The comparative ending '-er' was added to create a word meaning 'more first' or 'earlier'. The noun use — 'the former' (the first of two) — developed naturally from the adjective's meaning of 'first in order'. Meanwhile, the suffix '-former' (as in sixth-former) comes from a different root: 'form' meaning a school class, from Latin 'forma' (shape, arrangement), adopted into British school vocabulary in the 1500s.
