Syriac

ḥeltā - vagina (Brock. 232)

Syr. ḥeltā ‘vagina’ and Tgr. ḥəlelät ‘penis’ (hardly an Arabism in view of difference in meaning and pattern; pace [Leslau Loanwords 166]) can be as well compared to each other and to Arb. ‘canal of the penis’ still making a Sem. anatomic term with a possible meaning ‘canal of the genital organ’.

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