Forms
agna f (genitive agnae); first declension[1] Jerome has the ablative plural agnābus.[2]
Etymology
It is from Latin agnus (“lamb”) + -a, the feminine of the word for a lamb.[3][2][1] De Vaan traces agnus to Proto-Italic *agʷno- (“lamb”) and Proto-Indo-European *h₂egʷ-no- (“lamb”).[4] Cognate with Old Irish úan (“lamb”), Welsh oen (“lamb”) and Ancient Greek ἀμνός (amnós, “lamb”).[4]
Earliest recorded meaning
Köbler dates it from Cato.[5] Lewis & Short cite it first from Varro's work on agriculture.[2]
Semantic evolution
It is a ewe lamb, as opposed to a male lamb.[3][2] Horace speaks of a humble ewe lamb and Ovid of a trembling one.[2] The Vulgate has it in Genesis.[2] Church Latin glosses it a ewe lamb.[6]

Usage notes
A rare homograph agna, “ear of grain”, is known only from Paul the Deacon's epitome of Festus, which speaks of awned and awnless ears.[4][3][2] The OLD compares Ancient Greek ἄχνη (ákhnē, “chaff”), a Gothic word for chaff and English awn;[3] de Vaan notes that if it stands for an older *akna, it could go back with them to a derivative of the root Proto-Indo-European *h₂eḱ- (“sharp”), though the Greek is not a perfect formal match.[4]
