These are largely similar to the letters of the American manual alphabet. A few letters (upward G, sideward M and N) are oriented differently, with the result that D and G depend on a difference in hand shape that has been lost from informal ASL, and N looks like an ASL H. Several letters (hitchhiker-thumb A, clawed E, splayed F, nodding P, etc.) have minor differences that suggest a different "accent"; the thumb on A makes it more distinct from S than is American A. Four letters are radically different: H (the ASL '8'/'horns' handshape), J (a swiveling Y rather than I), X (uses two fingers, like a flexed ASL V), and T (just like the French F, but with the thumb on the inside of the index finger instead of on the outside).
