Morphology

tireless = tire (transparent) = tire + less

The word 'tireless' is transparently derived from 'tire' with the suffix '-less', indicating absence of the state of being tired.

Etymology

Tireless comes from tire ('to become tired') plus the ending -less ('without'). So it literally means 'without getting tired', which is why we use it for someone who keeps going with energy.
