Jibbali

ˀɛd - till, until (JL 1)

ˀ- instead of expected *ˁ- is irregular. See also Akk. adi for the unusual shift *ˁa- > a-.

PS
*ˁaday - up to, until (DUL 142)

It is not obvious that forms of the type (wV)d meaning “to, towards” are related to this preposition (Arakelova 2001:22). They are united into a separate lexeme, see *ˀVd/d.
