What's the difference between eccentric and irregular?

Eccentric


Definition:

  • (a.) Deviating or departing from the center, or from the line of a circle; as, an eccentric or elliptical orbit; pertaining to deviation from the center or from true circular motion.
  • (a.) Not having the same center; -- said of circles, ellipses, spheres, etc., which, though coinciding, either in whole or in part, as to area or volume, have not the same center; -- opposed to concentric.
  • (a.) Pertaining to an eccentric; as, the eccentric rod in a steam engine.
  • (a.) Not coincident as to motive or end.
  • (a.) Deviating from stated methods, usual practice, or established forms or laws; deviating from an appointed sphere or way; departing from the usual course; irregular; anomalous; odd; as, eccentric conduct.
