Root


Definition:

  • (v. i.) To turn up the earth with the snout, as swine.

A true root, however, may never reach the ground, but may be attached to a wall, etc., as in the ivy, or may hang loosely in the air, as in some epiphytic orchids.
  • (n.) An edible or esculent root, especially of such plants as produce a single root, as the beet, carrot, etc.; as, the root crop.

  • (n.) The cause or occasion by which anything is brought about; the source.
  • (n.) That factor of a quantity which when multiplied into itself will produce that quantity; thus, 3 is a root of 9, because 3 multiplied into itself produces 9; 3 is the cube root of 27.
  • (n.) The fundamental tone of any chord; the tone from whose harmonics, or overtones, a chord is composed.
  • (n.) The lowest place, position, or part.
  • (n.) The time which to reckon in making calculations.
