Sentence:  As it happens, the baraita in question speaks of the <WSD>tumtum</WSD> twice, introducing an apparent redundancy into the text. To be specific, Abbaye's solution, proposing an unusual interpretation of the first <WSD>tumtum</WSD> ("his testicles are evident from the outside"), allows for a different reading of <WSD>tumtum</WSD> in each of his two usages. 
Meaning of the word marked with <WSD> tags:  One whose gender can not be determined by a physical examination; a person lacking external genitalia; an androgynous person; sometimes a hermaphrodite.
