banter is of uncertain origin, first attested in late 17th-century English slang; Jonathan Swift called it a fashionable cant word of unknown derivation. The explanation preserves that uncertainty: the proposed comparisons illuminate the form, but they do not turn the word into a securely traced inheritance or borrowing. In modern use, the noun sense is "playful, teasing conversation", which keeps the etymology connected to the word's present dictionary value rather than treating it as a merely historical label. The wider word family includes derivatives such as bantering, banterer, showing how the same base continues to support neighboring English vocabulary.
