Many signs in the TÄ°D lexicon are two-handed signs. These signs are grouped under two categories, symmetrical, and asymmetrical signs, according to hand arrangement, that is, the relative complexity of handshape and movement features of the two hands. Symmetrical signs have the same handshape and similar movement in both hands, whereas in asymmetrical signs the dominant hand has movement but the second hand is the major location of the sign. Many of the two-handed signs are symmetrical.
