food: [OE] Food and its Germanic relatives, German futter ‘fodder’, Dutch voedsel ‘food’, and Swedish föda ‘food’, all go back ultimately to a prehistoric Indo-European base *pā-, *pī-, which also produced Latin pābulum ‘fodder’, Russian pisca ‘food’, and Czech pice ‘fodder’. The immediate source of all the Germanic forms was *fōth-, which had two important derivatives: *fōthram, which gave English fodder [OE] and (via Old French) forage [14] and foray [14] (etymologically probably a ‘search for food’); and *fōstrom, source of English foster.
