Editing Eccentricity (behavior) (section)

==Etymology==
From [[Medieval Latin]] ''eccentricus'', derived from [[Ancient Greek|Greek]] ''{{Transliteration|el|ekkentros}}'', "out of the center", from ''{{Transliteration|el|ek}}''-, ''{{Transliteration|el|ex}}''- "out of" + ''{{Transliteration|el|kentron}}'', "center".<ref>{{Cite web |title=Definition of ECCENTRIC |url=https://www.merriam-webster.com/dictionary/eccentric |access-date=2023-01-25 |website=merriam-webster.com |language=en}}</ref> ''Eccentric'' first appeared in English essays as a [[neologism]] in 1551, as an astronomical term meaning "a circle in which the earth, sun, etc. deviates from its center." (See [[Orbital eccentricity]].) Five years later, in 1556, an adjective form of the word was used. In 1685, the definition evolved from the literal to the figurative, and ''eccentric'' is noted to have begun being used to describe unconventional or odd behavior. A noun form of the word – a person who possesses and exhibits these unconventional or odd qualities and behaviors – appeared by 1832.
