Esperanto manual alphabet

The letters are all to be signed upright with a straight wrist, and palm outward, so for example the G resembles D, as in the French manual alphabet, although the D fingers are more open (like O) and the index finger is shorter.

None of the letters involve motion (again like the static wrist this is to allow greater accessibility for certain disabled groups), so J and Z are distinct from other alphabets: J is like a Cyrillic J; and Z has the form of an ASL 3 (which appears to be unique to Signuno, and may have its origins in Cyrillic letter З (z) being similar in shape to the number 3).

Other differences from the American manual alphabet are:[1] The diacritic letters Ĉ, Ĝ, Ĥ, Ĵ, Ŝ, Ŭ are sometimes derived from their base letters: Unlike in Gestuno, Signuno digits are all made on a single hand.

As in ASL, 100 and 1000 are signed as the Roman numerals C and M. For hours and months, there are additional sign for 11 and 12, which have the shapes of the letters Ĝ (11) and L (12) but turned so the palm faces the signer.
