沱 (tuó) is not commonly used as an independent word. It appears primarily in the compound 滂沱 (pāngtuó), which describes torrential rain or (in 涕泗滂沱) profuse tears, and in river names like 沱江 (Tuó River). The POS listed here is 'classifier (g)', but no standard classifier use of 沱 exists; the dictionary gloss 'tearful / to branch (of river)' fits noun or verb contexts, not a measure word.
