adjective (neuter nominative singular sotabbaṁ); gerundive form of √su + i (√ śru 'hear')
Analysis. so-: variant stem of suta- (heard, sound); -bba: gerundive suffix indicating 'fit for, worthy of, to be' — the word marks something as an appropriate object of hearing or worthy of audition.
Etymology. From √su (Sanskrit √śru, 'hear'), cognate with English 'shear' (to cut sound, i.e. perceive), Greek akouō (hear), and Sanskrit śruti (what is heard, revelation). The gerundive suffix -bba (from -tavya, Sanskrit -tavya) marks obligation or fitness, literally 'to be done': sotabba = 'to-be-heard', 'worthy of hearing'.
