IPA: /ˈpɑːrləs/
KK: /ˈpɑr.ləs/
Full of danger or risk; perilous.
Starting a new business can be a parlous venture in uncertain economic times.
Parlous originates from Middle English 'perilous' (meaning dangerous), which is derived from Old French 'perilleux' (meaning perilous or dangerous), itself from Latin 'periculosus' (meaning full of danger). The word 'parlous' means full of danger or risk.
Think of 'perilous' as a word that describes something 'full of danger' — that's why 'parlous' means something that is risky or dangerous.
