Word Nuance & Usage

'Sound' is a homonym representing four distinct etymological roots: acoustic vibration (from Latin 'sonus'), health or validity (from Old English 'gesund'), a coastal inlet (from Old English 'sund'), and measuring depth (from Old French 'sonder'). As an adverb, 'sound' is restricted almost exclusively to the collocation 'sound asleep', whereas 'soundly' is used in all other contexts.

Word Origin & Etymology

The acoustic noun and verb derive via Anglo-Norman from Latin 'sonus' (noise, tone). The adjective meaning healthy or reliable comes from Old English 'gesund' (safe, whole), while the geographical noun derives from Old English 'sund' (swimming, strait of water).
