Body_part

With some verbs in this frame, the Body_part involved in the action is specified by the meaning of the verb and cannot be expressed separately. For example, Pat yawned (*his mouth). With others, the Body_part is specified by the verb but can optionally be expressed separately, although its presence is generally redundant, as in Pat nodded (his head). A few verbs have a default Body_part which need not be expressed, but can be overridden by the expression of some other Body_part. Pat waved (his arms). (The objectless version of the sentence, Pat waved, is a blend with communication.) The remainder of the verbs require a Body_part to be expressed in a separate constituent: Pat rolled his eyes. Body_part generally occurs as the direct object.
