the.com/purposelessness

means The state of having no aim, direction, or reason behind what you're doing — the unmoored feeling of action (or inaction) with nowhere to go.

from Built from 'purpose' (from Old French 'porpos', rooted in Latin 'proponere' — to put forward, propose, set out as a plan) plus the negating suffix '-less' and the noun-forming '-ness'. So the word is literally stacked negation: a plan, un-made, turned into a condition. Nothing exotic in the history — just English's favorite trick of bolting 'lessness' onto a good solid Latin noun until the emptiness itself sounds official.
