IPA: /ˈmɒnəkl/
KK: /ˈmɒnəkl/
Describing someone who wears a single eyeglass, typically held in place by the eye socket.
The gentleman was monocled, giving him a distinguished appearance.
Monocled is formed from "mono-" (meaning one) and "cle" (from the Greek "kleis", meaning to close or to shut). The word describes something that has one lens or eye covering, typically referring to a single eyeglass lens.
Think of 'mono-' meaning one, and 'cle' relating to something that closes or covers. This helps you remember that 'monocled' refers to having one lens.
