## Definition

unusual or specific to one particular person or thing. You use this word to describe habits, tastes, or methods that are unique to someone and might seem a bit strange to others.

For teachers: peculiar to a specific individual, group, or thing. The term frequently describes behaviours, methods, or characteristics that deviate noticeably from the norm in a highly personal way.
