brotherly

the word 'brotherly' is a transparent english formation from the native germanic root 'brother' and the adjectival suffix '-ly'. the old english noun 'brōþor' descends from proto-germanic 'brōþēr', which itself derives from the proto-indo-european 'bʰréh₂tēr', a fundamental kinship term. the suffix '-ly', from old english '-līc', originally meant 'body' or 'form', and its use to create adjectives meaning 'having the quality of' is a common germanic pattern. thus, 'brotherly' literally means 'having the form or character of a brother', a sense which has remained consistent from its old english origins to its modern abstract usage denoting familial affection and camaraderie.
