'spenders' is the plural of 'spender', which comes from the verb 'spend', originating from Old English 'spendan', which was borrowed from Latin 'expendere', where 'ex-' meant 'out' and 'pendere' meant 'to weigh'.

'spend' changed from the Old English word 'spendan', which came from Latin 'expendere', and eventually became the modern English word 'spend'. 'Spender' was formed by adding the agent suffix '-er', and 'spenders' is its plural form.

Initially, 'spend' meant 'to pay out or weigh out money', but over time it evolved into its current meaning of 'to use or pay out money'. 'Spender' refers to a person who spends, and 'spenders' to multiple such people.
