fry: Fry ‘cook in fat’ [13] and fry ‘young fish’ [14] are quite distinct words. The former comes via Old French frire from Latin frīgere, a cooking term which covered what we would now distinguish as ‘roasting’ and ‘frying’. It goes back ultimately to Indo-European *bhreu-, which also produced Latin fervēre ‘boil’ (source of English fervent).

Its past participle frictus formed the basis of Vulgar Latin *frīctūra, from which, via Old French, English gets fritter [14]; and the past participial stem of the French verb, fris-, may lie behind English frizz [17]. Fry ‘small fish’ may come from Anglo-Norman frie, a derivative of Old French freier ‘rub, spawn’, which in turn goes back to Latin frīgere ‘rub’.
