| ~ north star, polar star, polaris, pole star, polestar | the brightest star in Ursa Minor; at the end of the handle of the Little Dipper; the northern axis of the earth points toward it. |
| ~ star | (astronomy) a celestial body of hot gases that radiates energy derived from thermonuclear reactions in the interior. |
n. (communication) | 4. variable | a symbol (like x or y) that is used in mathematical or logical expressions to represent a variable quantity. |
| ~ symbol | an arbitrary sign (written or printed) that has acquired a conventional significance. |
| ~ placeholder | a symbol in a logical or mathematical expression that can be replaced by the name of any member of specified set. |

| ~ multivariate | pertaining to any procedure involving two or more variables. |
| ~ protean | taking on different forms.; "eyes...of that baffling protean grey which is never twice the same" |
| ~ shifting | continuously varying.; "taffeta with shifting colors" |
