ETYMOLOGY
from sinister: from Old French senestre, sinistre or Latin sinister (left, left-hand)
EXAMPLE
“… That which still makes her mirth to flow,
Is our sinister-handed woe,
Which downwards on its head doth go,
And, ere that it is sown, doth grow.
This makes her spleen contract,
And her just pleasure feast:
For the unjustest act
Is still the pleasant’st jest. …”
