English meaning : to rinse, to wash out [L.Zhou]
Russian meaning[s]: 1) полоскать рот; чистить зубы; промывать; 2) размывать
Comments: In MC we would rather expect ṣǜ; ṣǝ̀w is due to confusion of -ǝ̀w and -ǜ after retroflex initials. The character is also read *srōk-s, MC sл̀w id. Standard Sino-Viet. is tấu / thấu; the form sục either reflects an unattested MC variant *ṣạuk ( < *srōk without the final *-s), or else is just a chance coincidence.
