Of, relating to, or characteristic of goats; having the nature or qualities of goats.
From 'goat' + '-ly' (Old English suffix '-lic' meaning 'of the nature of'). Note: '-ly' for adjectives versus '-ly' for adverbs from adjectives are distinct morphemes.
This is a rare word that shows English's historical ambiguity—'-ly' can mean both 'having the quality of' (goatly = goat-like) AND 'in the manner of' (quickly = in a quick manner), which caused confusion over centuries!
