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.
Noeldeke 1886, 726 tentatively connected the Akkadian–Aramaic isogloss *tkl (considered to be a secondary derivation from PS *wkl) with PES *tkl “to fix, to fasten, to plant” . This comparison, implying that Ethiopian preserves the primary meaning “to fix, to be well-fixed, reliable” and undermining the derivation from *w-k-l, is discussed and rejected by Leslau in CDG 573.

Cf. also wəkul ‘confisus, fretus,’ təwkəlt ‘confisio, fiducia, spes’ (LLA 920).
Likely an Arabism.
The relation to the present root is possible, since meanings of Tna. verb come remarkably close to those of the Akk. root.
