Morphology

bar + sinister

The literal constituents ('bar' = stripe/band; 'sinister' = left side) describe a heraldic mark (a stripe on the shield's left), so the phrase refers to a technical heraldry feature rather than directly to birth status. The conventional meaning 'illegitimacy' is historical and idiomatic, not predictable from the words alone, so a B1 learner who knows the constituents would unlikely infer the MWE's meaning.

Etymology

Bar sinister originally named a diagonal stripe on a shield: the word bar means a narrow band and 'sinister' was the old word for 'left', so the stripe ran from the top right to the bottom left of the shield and the phrase refers to that diagonal band.
