Sense: verb/1
All four can describe getting something, but only 'bought' and 'purchased' specifically mean paying money. 'Bought' is the everyday choice — neutral in register and used in any conversation, from groceries to houses. 'Purchased' carries the same core meaning but feels formal or business-like; you read it on receipts, contracts, and corporate emails ('the company purchased new servers'). 'Acquired' is broader and more formal still: it covers buying but also inheriting, winning, or otherwise obtaining, so it suits situations where the method is mixed or unstated ('the museum acquired the painting'). 'Got' is the casual catch-all — it can mean bought, received, or fetched, and only context tells you which. Compare: Beatrix bought a watch for her father (paid for it); Andrés got a watch for his birthday (received as a gift); the firm acquired its rival last year (probably bought, possibly merged).

Etymology
The form 'bought' comes from the Old English verb 'bycgan', meaning 'to pay for, acquire'. Its past tense was 'bohte', which survived into Middle English as 'boughte' and finally settled as modern 'bought'. The 'gh' in the spelling reflects a sound (a soft throat consonant) that English speakers stopped pronouncing centuries ago, leaving the silent 'gh' we still write today. The adjective use ('shop-bought cake') developed much later, by analogy with the past participle.
