Ultimate origin

Forms

baia f (genitive baiae); first declension[1][2]

Etymology

The palm branch is borrowed from Ancient Greek βαΐον (baḯon, “palm branch”).[1][3][2] Lewis & Short and Köbler connect the Greek word with a Coptic word for a palm branch.[4][3]

Earliest recorded meaning

Its only author is Jerome, writing against Jovinian about the priests of Egypt: their bed was woven of palm leaves, which are called baiae.[2][1][5][3]

Semantic evolution

It stayed a rare foreign word in Latin;[2][6] Du Cange notes that the Greek word lived on in later Greek.[5]

Timeline

  • c. 383–419/420 AD – Jerome uses it of the palm leaves of Egyptian priests.[2][3]

baia2 bay, harbour

Confidence
Uncertain
Formation
Borrowing
First attested
c. 560–636 AD, Isidore of Seville

Forms

baia f (genitive baiae); first declension[1][2] Köbler also records ⟨badia⟩.[3]

Etymology

The word for a harbour is of uncertain origin.[3] Köbler takes it as probably a borrowing from a language of the western Mediterranean, Iberian or Basque,[3] and Walde reports Uhlenbeck's view that the Romance word is of Basque origin;[7] Etymonline also mentions an Iberian source.[8] The medieval word was taken again from Old French baie.[9]

Isidore of Seville derived it from baiulō (“to carry a load”), because goods were carried there.[2][10][7]

Earliest recorded meaning

Isidore of Seville records it as an old word: the ancients called a harbour baiae, from the carrying of goods.[2][1][10]

Semantic evolution

It lives on in Italian baia and French baie.[2][1] Medieval charters use it for a bay or inlet of the sea:[9][5] a charter of 1210 speaks of fishing in the bays of an abbey,[5] and in 1427 a royal letter names Mount's Bay in Cornwall.[9] Köbler also gives the senses “inlet of a pond” and “mill dam”.[3]

English bay “inlet” comes from Old French ⟨baie⟩ and Late Latin ⟨baia⟩.[8]
