Letters are formed by a dominant hand, which is on top of or alongside the other hand at the point of contact, and a subordinate hand, which uses either the same or a simpler handshape as the dominant hand. Either the left or right hand can be dominant. In a modified tactile form used by deafblind people the signer's hand acts as the dominant hand and the receiver's hand becomes the subordinate hand.
