dactylology |
1 definition found From Webster's Revised Unabridged Dictionary (1913) [web1913]: Dactylology \Dac`tyl*ol"o*gy\, n. [Gr. da`ktylos finger + -logy.] The art of communicating ideas by certain movements and positions of the fingers; -- a method of conversing practiced by the deaf and dumb. Note: There are two different manual alphabets, the one-hand alphabet (which was perfected by Abb['e] de l'Ep['e]e, who died in 1789), and the two-hand alphabet. The latter was probably based on the manual alphabet published by George Dalgarus of Aberdeen, in 1680. See Illustration in Appendix.
