#3420 PTB *k-tu-k PENIS

This root, which has allofams both with and without a final velar stop, is found in several different subgroups of TB: NE Indian Areal Group, Himalayish, Asakian, Qiangic (including Xixia), and Baic. It has so far not been discovered in Lolo-Burmese or Karenic.

This root resembles #3423 PTB *tsu PENIS. The possibility that these two etyma might be one and the same is reinforced by the natural tendency of /t/ to become affricated before /u/, as witnessed by Japanese, where /tu/ is realized as [tsɯ].

This etymon also bears a perhaps accidental resemblance to #661 PTB *s‑tu VAGINA / VULVA.

An apparently prefixal k‑ is attested in Kham and Spiti. Cf. also the Tangut binome khǐu̱ thu.

A Lalung subtlety should be noted: the first elements of tu‑dar ‘penis’ and tu ki ku‑thi ‘testicle’ are to be assigned to #3420 PTB *k‑tu‑k PENIS; on the other hand, the first element of Lalung tu‑di ‘egg’ is from #1604 PTB *daw BIRD ‘bird’. This is somewhat confusing, since #300 PTB *d(w)əy EGG / TESTICLE sometimes means ‘testicle’ rather than ‘egg’.
