IPA: /kɜːrˈmʌdʒənli/
KK: /kɜrˈmʌdʒənli/
Describing someone who is bad-tempered, irritable, or difficult to please.
My curmudgeonly neighbor always complains about the noise from the children playing outside.
Curmudgeonly is derived from the word 'curmudgeon' (origin uncertain, possibly from the 17th century, with roots in Old French 'cormorche' meaning a miser or greedy person). The suffix '-ly' (meaning in the manner of) is added to describe someone who behaves like a curmudgeon. Thus, 'curmudgeonly' refers to someone who behaves in a miserly or grumpy manner, akin to a curmudgeon.
Think of a 'curmudgeon' as someone who is grumpy or miserly, and remember that 'curmudgeonly' describes someone acting in that same grumpy manner.
