Origin of eccentricMiddle English eccentrik ; from Medieval Latin eccentricus ; from Late Latin eccentros, out of the center, eccentric ; from Classical Greek ekkentros ; from ek-, out of (see ex-) + kentron, center

- an odd or unconventional person
- Departing from a recognized, conventional, or established norm or pattern. See Synonyms at strange.

- a. Not having the same center: eccentric circles.b. Having the axis located elsewhere than at the geometric center.
- One that deviates markedly from an established norm, especially a person of odd or unconventional behavior.
- Physics A disk or wheel having its axis of revolution displaced from its center so that it is capable of imparting reciprocating motion.
Origin of eccentricMiddle English eccentrik, planetary orbit of which the earth is not at the center, from Medieval Latin eccentricus, not having the same center, from Greek ekkentros : ek-, out of; see ecto– + kentron, center (from kentein, to prick; see kent- in Indo-European roots).

(comparative more eccentric, superlative most eccentric)

- Not having the same goal or motive.
From Middle French excentrique, from Medieval Latin excentricus, from Ancient Greek ἔκκεντρος (ekkentros, “not having the earth as the center of an orbit”), from ἐκ (ek, “out”) + κέντρον (kentron, “point”)
eccentric - Computer Definition
- Elliptical or off-center, rather than perfectly circular with a precisely centered axis. Eccentricities in the core of an optical fiber can cause signal attenuation and distortion.
- A euphemism for someone who is crazy and rich, as opposed to being just plain crazy like the rest of us.
