Forms

ambi- [1] Varro has the spelling ambe-.[2]

Etymology

It is the fuller form of amb-, inherited from Proto-Italic *ambi, inherited from Proto-Indo-European *h₂m̥bʰi (“to, around”); its cognates are listed there.[3][1] In compounds with nouns and adjectives it was often understood as if it came from ambō “both”,[4] and Wiktionary treats it there as the stem of that word with the linking vowel ⟨-i-⟩.[1]

Earliest recorded meaning

De Vaan finds the old prefix only in glosses and grammarians: Varro has ambiegnus, “with lambs on both sides”, and ambecīsus, a cut on both sides, and Festus ambiaxiō.[3][5][6]

Semantic evolution

Later compounds were formed on ambō beside older compounds in bi-: ambidēns beside bidēns, and ambifāriam beside bifāriam.[3] Apuleius uses ambifāriam of an argument that traps an opponent either way,[5][6] and ambidexter, “using both hands as the right”, appears in the Itala.[6] In Medieval Latin ambidexter could mean “double-dealing”.[7][8]

Timeline

  • 116–27 BC – Varro records ambiegnus.[5][6][3]
  • c. 125–175 AD – Apuleius uses ambifāriam.[5][6]
  • after 220 AD – ambidexter appears in the Itala.[6]
