Note:
1. Some signers feel there is a meaning difference between two of the different forms of this sign: one is ‘tell’ and the other is ‘say’. However, corpus recordings shows signers using both palm orientations while mouthing either ‘tell’ or ‘say’. Indeed, most signers combine either mouthing with both forms at different times. So it is hard to support the claim that they are really two different signs rather than one sign that varies.
