Aimless means having no purpose or direction. Moving, and not towards anything.
It describes wandering, conversation and whole periods of life, and aimless drifting is a phrase that carries real melancholy. The word is gentler than pointless, since aimless describes the absence of a goal rather than the absence of value, and an aimless afternoon can be a pleasure. The adverb aimlessly usually attaches to a verb of movement. Purposeless is the formal equivalent.
