*tbˁ - to set out, to depart (Kogan 2015:342)

Uncertain. Akk.-Ugr. *tbˁ ‘to set out, to depart’ is probably related to Arb. tbˁ ‘to follow’, but the semantic gap underlying this comparison contrasts sharply with the virtual semantic identity between Akkadian and Ugaritc.

Akkadian
tebû - to get up, to rise; to set out, to depart, to leave (CAD T 306, AHw. 1342)

Cf. Ugr. tbˁ ‘to go, leave, depart’, Arb. tbˁ ‘to follow’.

Ugaritic
tbˁ - to go, leave, depart (DUL 857)
Arabic
tbˁ - to follow (Lane 293)
Mehri
tūba - to follow (ML 399)

Likely an Arabism.

Jibbali
tēˁ - to follow (JL 269)

Likely an Arabism.
