Plural of bargainer; multiple people who negotiate or haggle over prices and terms.
Simple plural formation of 'bargainer' (bargain + -er + -s). The '-s' plural marker derives from Old English and remains the standard plural ending.
Plurals seem simple, but English used to have many different ways to pluralize words (like 'oxen' and 'children'), and we've largely standardized on '-s,' which shows how language simplifies patterns over centuries.
