Etymology. Sota (ear) descends from √śru (Sanskrit śrotra), the Indo-European root *srew- 'to flow' (English stream, German Strom), originally the flowing of sound into the ear. Dhātu (element, state, constituent) from √dhā 'to place/establish' (English do, Latin facere), denoting a fundamental stratum or quality that 'stands firm' (see sam + ā + dhā in samādhi). The compound is a learned Abhidhamma term for the ear's essential nature as an element.
