The Spanish word 'cotizante' (meaning 'contributor') comes from the Spanish verb 'cotizar' ('to quote' or 'to pay a share') combined with the present participle suffix '-nte'. The verb 'cotizar' was borrowed from French 'cotiser' meaning 'to pay a share', which developed from the Old French noun 'cote' meaning 'quota' or 'share'. Going further back, we can trace this to the Latin word 'quotus' meaning 'how much', which was used to ask about quantities or portions.

A simpler and more common related Spanish word is the verb 'cotizar', which means 'to quote (a price)' or 'to pay one's share'. You might hear this in financial contexts like 'cotizar en la bolsa' (to be quoted on the stock exchange) or in social security contexts like 'cotizar a la seguridad social' (to pay social security contributions).

The English word 'quote' is a distant cousin of 'cotizante', as both can be traced back to the Latin 'quotus'. While 'cotizante' developed through French to mean someone who contributes or pays their share, 'quote' developed its meaning of citing someone's words or stating a price. The English word 'quota', meaning a fixed share or limit, is also related and actually maintains a meaning quite close to the original Latin sense of 'how much'.
