American Sign Language uses about twenty movements. These include lateral motion in the various directions, twisting the wrist (supinating or pronating the hand), flexing the wrist, opening or closing the hand from or into various handshapes, circling, wriggling the fingers, approaching a location, touching, crossing, or stroking it, and linking, separating, or interchanging the hands.
The signal is performed by holding one hand up with the thumb tucked into the palm, then folding the four other fingers down, symbolically trapping the thumb by the rest of the fingers. It was designed intentionally as a single continuous hand movement, rather than a sign held in one position, so it could be made easily visible.
Six types of signs have been suggested: one-handed signs made without contact, one-handed signs made with contact (excluding on the other hand), symmetric two-handed signs (i.e. signs in which both hands are active and perform the same action), asymmetric two-handed signs (i.e. signs in which one hand is active and one hand is passive) where ...
The sign is an informal expression of any of several positive feelings, ranging from general esteem to love, for the recipient of the sign.A similar-looking but unrelated variation in which the thumb is toward the palm appears in heavy metal music culture as a "horns" hand-sign (though the thumbs extended version is sometimes used) and in college football as a sign of support for various teams ...
The phonetics of verbal speech and sign language are similar because spoken dialect uses tone of voice to determine someone's mood and Sign Language uses facial expressions to determine someone's mood as well. Phonetics does not necessarily only relate to spoken language but it can also be used in American Sign Language (ASL) as well.
For example, an ILY hand may 'lift off' or 'land on' a horizontal B hand to sign an aircraft taking off or landing; a 3 hand may be brought down on a B hand to sign parking a car; and a G hand may be brought toward a V hand to represent one person approaching two.
But this practice confuses signals with symbols. Sound and light are analogue signals, whereas mouth and hand gestures are discrete symbolic entities. A sound or light signal is subject to random noise, whereas the image of the gesture is subject to regular distortion, as when a signer's hand is viewed from different angles. In speech, the ...
Classifiers differ from signs in their morphology, namely that signs consist of a single morpheme. Signs are composed of three meaningless phonological features: handshape, location, and movement. Classifiers, on the other hand, consist of many morphemes. Specifically, the handshape, location, and movement are all meaningful on their own. [2]
