vendere

Vendor comes from the Anglo-French vendour, from the Latin venditor (seller), from vendere (to sell). Vendere itself is a contraction of vēnum dare (to give for sale), from vēnum (sale, something for sale). The word entered English in the early sixteenth century. A vendor is, simply, a person who sells. The word has remained remarkably stable — five centuries, one meaning.

The Latin root vēnum connects selling to several unexpected English words. Venal (from vēnālis: for sale) means corruptible — someone whose integrity is for sale. Vendetta (from the Italian vendetta: revenge, from the Latin vindicta) shares the transactional logic: a vendetta is a debt of violence that must be repaid. Selling, corruption, and revenge all involve exchange. The Latin root links them.

In modern commercial English, vendor has taken on a specific corporate meaning: a supplier, a third-party provider. 'Vendor management,' 'vendor relations,' 'vendor lock-in' — these are procurement terms, not street-market terms. The word that meant a person selling goods now means a company selling services. The scale changed. The transaction did not.

Street vendor — the oldest meaning — persists. Hot dog vendors in New York, fruit vendors in Bangkok, newspaper vendors in London — the word still names the person who stands in a public space and sells. The corporate vendor and the street vendor share a word and almost nothing else.
