Geez

ḥǝmŝ, ḥəms - uterus, womb, pubes (CDG 234)

ŝ points to *ŝ unless a graphic variant of s (this and other examples of Sem. *ṯ > Gez. ŝ are treated in [Voigt Interdentale 105-6 et passim]).

PS
*ḥamṯ- - lower belly, uterus, womb (SED I No. 122; Kogan 2011: 217)
Phonetically not without difficulties: only Ugr. and MSA forms definitely point to *-ṯ as the third radical while reflexes in other languages are either not indicative (Akk., Hbr., M. Eth.) or irregular (Arm.).
