veteran: [16] Veteran comes via French vétéran from Latin veterānus ‘old’. This was a derivative of vetus ‘old’, which is the ancestor of French vieux, Italian vecchio, and Spanish viejo. It went back ultimately to Indo-European *wetus- (source also of Latvian vecs ‘old’). This may be related to Greek étos ‘year’, in which case ‘old’ could derive from an ancestral meaning ‘full of years’.
