dreamless

The word 'dreamless' is a transparent Modern English compound formed from the native Germanic elements 'dream' and the suffix '-less'. The core noun 'dream' itself underwent a significant semantic shift from its Old English meaning of "joy, music, revelry" to its current sense related to sleeping visions, a change influenced by related Norse terms. The suffix '-less', meaning "without," has remained remarkably stable from its Proto-Germanic origin lausaz. When combined, the literal construction "without dreams" accurately describes both a physiological state of deep, undisturbed sleep and, by extension, a metaphorical state devoid of aspiration or imagination.

Structure: dream (vision in sleep) + less (without) - dream: From Old English drēam (joy, music, noisy merriment), later evolving to mean "a sequence of thoughts or images during sleep." Its functional role is the core noun/root. - less: From Old English -lēas (devoid of, free from), an adjective-forming suffix. Its functional role is a privative suffix indicating absence.
