Thus virile, too, I guess

There might be a connection between Latin vir, viri, 'man' (and via 'way' and vis, vis, 'strength, force, vigor, power', from PIE *wei-, vi:- 'to take the straight route; to be powerful' pp.1123f., and Latin virga, virgae, 'twig; rod, switch', but Pokorny in his IEW gives two separate roots: *weis-g- 'to spin, turn, twist' (augmented with g), p.1134. The use of virga as a euphemism for the obscene mentula 'membrum virile' does exist, perhaps by folk etymology; cf. virgo (possibly from the same (second root above) 'virgin').

Ceci n'est pas un seing.
