(Latin, on the left hand). According to augury, birds, etc., appearing on the left-hand side forbode illluck; but, on the right-hand side, good luck. Thus, corva sinistra (a crow on the left-hand) is a sign of ill-luck which belongs to English superstitions as much as to the ancient Roman or Etruscan.(Virgil: Eclogues, i. 18.)
That raven on yon left-hand oak (Curse on his ill-betiding croak) Bodes me no good.
Sinister. (See Bar Sinister.)
