Bib
late 16th century: probably from bib2.
wiktionary
Originally verb sense “drink heartily”, from Middle English bibben, either from Latin bibō(“I drink”) or of imitative origin. Noun sense (clothing) presumably either because worn while drinking, or because the clothing itself “drinks up” spills. [1]
bib (third-person singular simple present bibs, present participle bibbing, simple past and past participle bibbed)
etymonline
bib (n.)
linen worn over the breast, especially by children, to keep the front of the dress clean while eating, 1570s, from verb bibben "to drink" (late 14c.), which is perhaps imitative of lip sounds; or else [Skeat] it is from Latin bibere "to drink" (from PIE root *po(i)- "to drink"). If the latter, it is difficult now to say whether this is because it was worn while drinking or because it "soaked up" spills.
