IPA: /ˈnɒbɪli/
KK: /ˈnɑbɪli/
In a way that is stylish or elegant, often with a sense of superiority or pretentiousness.
She dressed nobbily for the gala, impressing everyone with her elegant style.
Nobbily is derived from "nob" (from Old English "nobbe", meaning a small lump or protuberance) and the suffix "-ily" (meaning in a manner). The word "nobbily" describes something that is done in a manner that is lumpy or has protuberances.
Think of a small 'lump' ('nob') and how it can be done 'in a manner' ('-ily') that is bumpy or uneven.
