{naDev Da’elpa’}. 

If you asking about {naDev}, it’s a noun in Klingon not an adverbial, and thus can be the object of a verb.  If you’re asking whether {‘el} takes an object, it does; e.g.:

tach vI'el, HItlhej
Let's go to the pub. (RT)

Hevetlh wIghoSchugh veH tIn wI'el maH'e'

that course will take us into the [Great] Barrier as well! (ST5)

neHmaH Da'el net tu'
Caught breaching the Neutral Zone. (MKE)
