IPA: /ʌnˈbɔt/
KK: /ʌnˈbɔt/
Not purchased or acquired by buying.
The unbought items remained on the shelf after the sale.
Unbought → It is formed from "un-" (meaning not) and "bought" (the past participle of "buy", from Old English "bycgan", meaning to purchase). The word "unbought" means not purchased or not acquired through buying.
Think of 'not' ('un-') having something that is 'purchased' ('bought') — that's why unbought means something that hasn't been bought.
