Body Classifier (BCL) is a type of classifier that refers to a part of the body within the frame of the signing area. E.g. arm, head, etc. Unlike BPCL (body part CL), it is used directly by the part of a body.
For example, hands "holding a person", tapping on a person's shoulder, etc.
The difference between BPCL and BCL is basically the use of a part of the body directly and indirectly.
For example, when a person nods using the head that is nodding, it is an example of BCL. On the other hand, when a person uses the dominant classifier handshape "S" that represents the head and this handshape moves nodding. It is an example of BPCL.
