Origins

From Proto-Italic *olenā, presumably from Proto-Indo-European *Heh₃l(e)n-, from the root *Heh₃l- (“to bend”), although this reconstruction remains uncertain. Related to Old Armenian ուլն (uln, “neck”), Gothic 𐌰𐌻𐌴𐌹𐌽𐌰 (aleina, “cubit”), Old Church Slavonic ланита (lanita, “cheek”), Ancient Greek ὠλένη (ōlénē, “elbow”), Sanskrit अणि (aṇi, “the point of a needle”), Albanian llërë (“upper arm”), Welsh elin (“forearm; elbow”).
