Unlike other adverbials, neH follows the verb which it modifies. The semantic effect is one of trivializing the action.

qama' vIqIppu' neH I merely hit the prisoner. 
(qama' prisoner, vIqIppu' I hit him/ her)

Duj yIQotlh neH Just disable the ship! 
(Duj ship, vessel, yIQotlh disable it!)

The use of neH in the preceding sentence implies that the ship is to be disabled, but not damaged further.

Also unlike the other adverbials, neH can follow a noun. In such cases, it means only, alone.

yaS neH only the officer, the officer alone

jonta' neH only the engine

Hagh qoHpu' neH only fools laugh

There is also a negative form of this adverb that can also be used after a noun to mean not only.

chaH neHHa' wovmoH jul the sun lit up not only them

tlhIngan Hol neHHa' vIjatlh I speak not only Klingon
