semel (not comparable)[1]
Etymology
It is from Proto-Indo-European *sem- (“one”), the root of semper, simplex and singulī.[2][3][4] De Vaan reconstructs Proto-Italic ⟨*semali⟩ “alike, together” for simul, and Sihler derives ⟨semel⟩ from ⟨*sm̥-meh₁lom⟩ “one measure”.[5][1] Cognate with Sanskrit सकृत् (sakṛ́t, “once”), Ancient Greek ἅπαξ (hápax, “once”) and Gothic 𐍃𐌹𐌼𐌻𐌴 (simle, “once”).[2][5]
Earliest recorded meaning
The OLD's earliest citation is from Ennius, “once”.[2] Köbler dates Ennius 204–169 BC.[4]
Semantic evolution
It meant a single time, once, as in Ennius; in Cicero it began an enumeration (semel, iterum, tertiō) and meant once and for all.[2] In Plautus it marked a single event with a lasting consequence, “once, ever”, and in Seneca it meant at one go.[2]
British Medieval Latin used it for once, vel semel “just once”, and nōn semel “more than once”.[6]
