gook แปลว่า

From the manner whereby a small child, still developing its speech, would mispronounce /l/ (spoken with the tip of the tongue behind the teeth) as /ɡ/ (spoken with the back of the tongue on the palate), which happens if one tries to say look without moving the tongue forward, thus requiring less effort to speak. Compare also wook and wike for “look” and “like”, in which cases the tongue is stationary and only the lips move.
