Despite her talent, she was often called the uncomeliest of the performers.
Uncomeliest → It is formed from "un-" (meaning not) and "comely" (from Old English *cūmlic*, meaning pleasant or attractive) and the superlative suffix "-est" (meaning most). The word "uncomeliest" means the most unpleasant or least attractive.
Think of 'not' ('un-') being added to 'pleasant' ('comely') to remember that 'uncomeliest' means the most unpleasant.
