CLASSIFIERS

Definition of a classifier:

A set of handshapes that represent classes of things that share similar characteristics.  Classifiers are essentially used to modify nouns.  Classifiers, if used correctly, clarify the message, highlight specific details, and provide an efficient way of conveying information.

They can be used to:
    describe the size and shape of an object.
    represent the object itself.
    describe how it moves.
    describe how it relates to other objects and or people.

Rules:
Classifiers have to be introduced.   So, prior to using a classifier identify the object. If we are going to talk about Jane, who is not in the classroom - I'll spell her name.  Or if I'm talking about my sister, then I sign "sister" prior to using CL: 1 or CL: V.   (Sister, CL1: bumped-into old boyfriend)  Or if I'm talking about baseball, I'll identify the ball before using the CL:3-bent.

An effective classifier mimics the natural movement or shape of the referred object.  If using a CL: O-flat to represent a dinosaur, the head ought to jog/jab forward to represent the animal's long strides; or if using the same handshape for a cobra, the hand must mimic it's side to side dance.

Classifiers often work best in conjunction or tandem with other classifiers, if you want to provide exacting details.  For example, if you want to describe a couch, you can use the CL:V-bent (sign "sit) and then 2 CL:C (palms down, hands moving outward).

Classifiers appeal to the visual sensibilities.  It is  the conceptualistic story, art in motion.  The goal is to clarify, paint a precise picture of your object looks like, of what happened.  In a car crash, what happened to the car?  Did the driver hit you from the side, the front?  What happened to you? Did you hit your head on the stirring wheel or fly through the window?

Also:
While I have attempted to create a comprehensive list of classifiers, this list is a work in progress and therefore not complete.  It is also not meant to be representative, in its entirety, of all the classifiers that are being used in American Sign Language, or how they are being used.  I simply listed those that are either most common, or those that I've seen and/or used myself.

The best way to learn how to use classifiers is by getting out in the Deaf community and observe the masters.  Meet and chat with those who are native Deaf, CODA (children of deaf adults), SODA (siblings of deaf adults), and interpreters.  Engage in conversations, interact, and learn.
