KK: /ˈkrɒtʃɪti/
Someone who is easily annoyed or difficult to please, often acting in a cranky or whimsical manner.
My crotchety neighbor always complains about the noise from the kids playing outside.
Crotchety originates from the dialectal English word 'crotchet', which means a whim or a caprice, and is derived from the Old French 'croche', meaning a hook. The suffix '-y' indicates a characteristic. Thus, 'crotchety' describes someone who is characterized by whims or caprices, often in a grumpy or irritable manner.
Think of someone who is 'hooked' on their own whims ('crotchet') — that's why 'crotchety' means being grumpy or irritable due to those whims.
