ḥəlil- - orifice of the teat; the urethra (WTS 53)

Probably an Arabism that explains a very specified anatomic meaning similarity with Arb. But on the hand, it’s hardly an Arabism in view of difference in meaning and pattern; pace [Leslau Loanwords 166].

PS
*ḥil(Vl)- - canal (anat.), urethra (?) (SED I No. 115)
A difficult case with scarce attestation.
