experimental gismu x1 is a gesture/facial expression/body part motion/body language/expressive (nonverbal or nonvocal) feature/microexpression/stature/posture/sign/body signal [nonverbal expression made using only one's body parts and items on one's immediate person as extensions of the body in order to communicate; possibly nonlinguistic/extralinguistic] that conveys/expresses thought/emotion/command/idea x2 (nu/si'o; possibly text and other types) made using body part/utensil/object/at locus x3 in/by motion/action/means x4 Must be body-oriented; any other object involved is simply for the matter of convenience and acts as an extension of the body (and thus must be on the performer's immediate person at or near the locus of the gesture). Body language, posturing, and stature are usually considered to be nonlocalized (body-general), although they need not be (and technically are not in general). Must be externally visible and/or internally sensed. Any non-body-part utensil/item (including clothing) must function as an extension of the body in the gesture. Need not be conscious or performed by a person (note that agent/performer is not mentioned in this definition); can, but need not, be accompanied by vocalizations (not necessarily linguistic), but the gesture itself is not primarily noise-producing. Might include sign language words or cheremes, although a more explicit word for linguistically organized and “full” cheremes is preferred (and especially for the sign language as a whole). x1 is possibly best typed by nu and/or si'o. x4 might be best expressed as an event; for example, it could be "the event of the right hand touching the chest near the heart, with fist clenched" for a salute, whereas/wherein x3 would be merely the fist/hand (and the chest near the heart). Use cocygau for: x1 (agent) gestures; x1 agentively/actively makes gesture x2, communicating x3, performed with body part(s) x4 in motion x5. Proposed short rafsi: -coc-.
