A line from the movie A.I. Artificial Intelligence grates a bit with "articulated in limb".
The artificial being is a reality of perfect simulacrum, articulated in limb, articulate in speech, and not lacking in human response.
I am not sure what "limb" means in this sentence. If it refers to human appendages, shouldn't it be a count noun (according to various dictionaries) and be "limbs"? What does "articulated in limb" mean here?
