Other identifying terms: Active/inactive couple or person, for certain dances when it is descriptive, or impractical to use numbers.   (Often 3 or 5 couple sets, 2+1 mixers, Virginia reel variants, squares, or Scottish dances) Right hand / left hand (lady/gent) for squares 1st corner/2nd corner or right hand/left hand for contra corners (these are not necessarily neighbors, nor shadow/partner at set ends, nor are they precisely previous/current/next neighbors in a double progression) Inside/outside for mixers or couple dances Those who can, those who want, those who did/didn't Leader (for lines) Leads/Follows (squares, mostly) Was top/bottom on the list? Lone person/9 pin (mixers, odd number of dancer sets) A/B for royal (double) squares That's what springs to mind.  Neal  Sent from my T-Mobile 4G LTE Device
