IPA: /ɪˈnɛlɪɡənt/
KK: /ɪˈnɛlɪɡənt/
Not having grace or beauty; clumsy or awkward in appearance or style.
The design of the building was considered inelegant compared to its more modern neighbors.
Inelegant is formed from "in-" (meaning not) and "elegans" (from Latin, meaning tasteful or refined). The word describes something that is not tasteful or refined, hence lacking elegance.
Think of 'not' ('in-') combined with 'tasteful' ('elegans') to remember that 'inelegant' means lacking taste or refinement.
