sourly

the word 'sourly' is a transparent formation from the old english adjective sūr, which descends from the proto-germanic root sūraz, meaning 'sour, salty, bitter'. this root is likely connected to the proto-indo-european base meaning 'to be sour', which also gave rise to words like latin sūrus 'sour' and lithuanian sūras 'salty'. the adverbial suffix -ly originates from the old english -līce, derived from the noun līc meaning 'body, form', and evolved to denote 'having the form or manner of'. therefore, 'sourly' literally means 'in a sour manner', a semantic evolution that extended from describing a literal acidic taste to metaphorically characterizing a sharp, resentful, or disagreeable disposition.
