Explanation

Parlous is an adjective that means "dangerous," such as the parlous car trip with a new driver behind the wheel! The first syllable in parlous rhymes with far and is accented: "PAR-less." It means dangerous — something that is parlous might carry the risk or threat of harm, like a parlous experience of being in a boat during a rainstorm. Parlous and perilous are synonyms.
