Never stopping; continuing without pause, often in a way that is annoying or tiresome.
From Latin 'incessans' (not ceasing), from 'in-' (not) + 'cessans' (ceasing, from 'cedere,' to stop). Entered English in the 1500s.
The word 'incessant' perfectly captures parental exhaustion—an incessant crying baby, an incessant stream of questions—because the relentlessness without even a brief pause is what makes something mentally draining.
