Etymology

the word 'deathly' is a transparent english compound formed from the native germanic noun 'death' and the productive suffix '-ly'. the old english noun 'dēaþ' stems from the proto-germanic root 'dauþuz', which is itself derived from the proto-indo-European verbal root 'dheu-', meaning 'to die'. the suffix '-ly', originating from old english '-līc' meaning 'body, form', evolved to signify 'having the form or character of'. therefore, 'deathly' literally means 'having the qualities or appearance of death', a meaning that has remained consistent from its formation in middle english to its modern usage describing a profound resemblance to or association with death.
