Initialized sign

In sign language, an initialized sign is one that is produced with a handshape(s) that corresponds to the fingerspelling of its equivalent in the locally dominant oral language, based on the respective manual alphabet representing that oral language's orthography. The handshape(s) of these signs then represent the initial letter of their written equivalent(s). In some cases, this is due to the local oral language having more than one equivalent to a basic sign. For example, in ASL, the signs for "class" and "family" are the same (a basic sign for 'group of people'), except that "class" is signed with a 'C' handshape, and "family" with an 'F' handshape. In other cases initialization is required for disambiguation, though the signs are not semantically related. For example, in ASL, "water" it signed with a 'W' handshape touching the mouth, while "dentist" is similar apart from using a 'D' handshape. In other cases initialization is not used for disambiguation; the ASL sign for "elevator", for example, is an 'E' handshape moving up and down along the upright index finger of the other hand.

The large number of initialized signs in ASL and French Sign Language is partly a legacy of Abbé de l'Épée's system of Methodical Sign (les signes méthodiques), in which the handshapes of most signs were changed to correspond to the initial letter of their translation in the local oral language, and (in the case of ASL) partly a more recent influence of Manually Coded English.^[1]
