sleeplessness

the word 'sleeplessness' is a layered english compound built entirely from germanic elements. its core, 'sleep', originates from the old english 'slæp', which traces back to proto-germanic 'slēpaz' and ultimately to the proto-indo-european root 'sleb-' meaning 'to be weak, sleepy'. the adjectival suffix '-less', from old english '-lēas', originally meant 'free from' or 'devoid of', attaching to nouns to form descriptive terms. finally, the abstract noun suffix '-ness' is added to 'sleepless' to concretize the quality into a defined state or condition. thus, the word's construction follows a transparent logical path: from the state of sleep, to the adjective describing the absence of it, and finally to the noun naming the condition of that absence.
