Past tense of 'farrow,' meaning a mother pig gave birth to a litter of piglets.
From Old English 'fearh' (young pig) and Old High German 'farre' (bull calf). The verb form developed in Middle English to describe the act of birthing in pigs specifically.
Pigs have been so integral to human civilization that multiple Indo-European languages developed specific words just for piglet births—'farrow' appears nowhere else in nature, it's purely about domestic animals.
