#700 PTB *dak ARM / HAND

The Nocte forms require no further comment. Of special interest is the Jingpho form lətáʔ, for which several explanations have been offered (cf. STC nn. 102, 109, 137). In my opinion, what happened was, after the obstruentization of original l to t in Jingpho, yielding taʔ, the form was reprefixed by the general root *lak, here reduced to . Note that in Jingpho, a secondary prefix lə‑ occurs in many verbs describing action with either the hands or the feet (see my portion of STC, n. 308 and O. Hanson 358-85). The Tangut and Ergong forms seem to have a similar origin.

Another explanation might be in terms of metathesis, **d‑lak > *l‑dak, in order to avoid the disfavored dl‑ cluster.
