anceps (genitive ancipitis); third-declension one-termination adjective[1]
Etymology
It is from ambi- (“on both sides”) and -ceps (“headed”), from caput “head”.[2][1][3] Plautus has a nominative ⟨ancipes⟩.[2][4]
Earliest recorded meaning
The OLD's first citations are from Plautus, of a two-edged weapon and double dangers.[2] Köbler dates Plautus c. 250–184 BC.[5]
Semantic evolution
It meant two-headed, facing two ways, as Ovid's two-faced Janus, of weapons two-edged, as in Plautus, and exposed on both sides.[2][3] It meant twofold, double, having two meanings, of amphibians living two lives, of war fought on two fronts, as in Varro, and of dangers arising from two sides.[2] It meant wavering, undecided, of battles indecisive, as in Virgil and Livy, of outcomes doubtful, critical, and dangerous, perilous, with in ancipitī “in danger”.[2] It meant ambiguous, of persons unreliable or undecided, as in Sallust.[2] Döderlein says dubius and ambiguus concern doubt about success, anceps danger.[6]
In Ecclesiastical Latin it meant two-edged, double, uncertain, ambiguous, dangerous.[7] In Medieval Latin it meant a two-edged weapon, a two-handed sword.[8][9] English prosody uses the phrase syllaba anceps.[1]
