Having no purpose, aim, or meaning; serving no useful function. Lacking a sharp point or tip (literal sense, rarely used).
From 'point' + '-less' suffix. Originally meant literally 'without a point' (as in a blunt weapon), but by the 17th century had developed the figurative meaning of 'without purpose.'
The word 'pointless' shows how English loves to extend physical descriptions into abstract concepts - just like 'sharp' minds and 'dull' people. Interestingly, something can be pointless in the literal sense (like a round ball) but still have great purpose, showing how the figurative meaning has completely taken over.
