*ŝVm- - kind of mouse, rat (SED II No. 214)

Not very reliable since ŠU in the Eblaite form points to ṯ rather than *ŝ or *š in the protoform which is not compatible with š in Arb.

Akkadian

ušummu - dormouse

Var. šummu (known from later texts only). According to Englund 1995 45 ff. u. is to be identified with the bandicoot rat rather than dormouse as previously thought.

Arabic

šīm- - rat (BK 2 1300, TA 32 487)

Cf. also šayham- ‘porcupine’ (BK 1 1283, LA XII 328)
