PS
*wkl - to (en)trust, to rely (DRS 539, Kogan 2015:239, EDA II)

PNWS *ykl ‘to be able’ may be related.

According to a broad consensus summarised in Kouwenberg 2010a, 454 and Kogan 2015, 101, Akk. takālu is a diachronically secondary verb going back to PS *wkl “to trust, to rely”. The same type of secondary root has been independently produced in Arabic and Aramaic. As reasonably argued by Kaufman 1974, 106, the high proliferation of *tkl in Aramaic (notably, in opposition to its modest presence in Arabic) may be due to Akkadian influence on Aramaic or even to a direct borrowing from Akkadian.

PS
*wḳd/*ḳwd - to burn (Kogan 2015:398)
PS *wḳd/*ḳwd ‘to burn’ is relatively well attested (DRS 601), but as opposed to Aramaic neither Hbr. yḳd, nor Akk. ḳâdu, nor Arb. wqd can be said to function as the basic verbs with the meaning “to burn” (intransitive) in the respective languages.
