PS

*ˁmd - to support; to stand (HALOT 840)

Akkadian
emēdu - to lean against sth, to stand by; to place (CAD E 138)
Ugaritic
ˁmd - support or foot of a wall (DUL 164, Watson 2007: 80)
a regular reflex of PS *ˁmd, borrowing from Akk. imdu ‘stanchion, support’ (CAD I 109) is quite unlikely (Pardee 2000: 882) (Kogan 2015: 356).
Hebrew
ˁmd - go up before, stand up; to stand; to be motionless (HALOT 840)
Arabic
