Answer and Explanation:
The word <em>eccentric</em> (adj) has different meanings. According to Merriam Webster Dictionary, some of them could be :
- deviating from conventional or accepted usage or conduct especially in odd or whimsical ways, e.g., <em>an eccentric millionaire.</em>
- deviating from an established or usual pattern or style, e.g., <em>eccentric products.</em>
- deviating from a circular path (especially: ELLIPTICAL sense) e.g., an <em>eccentric orbit. </em>
- located elsewhere than at the geometric center, e.g., <em>an eccentric wheel.</em>
The word has also its origins in different old languages, especially from the Ancient Greek <em>ἔκκεντρος</em> (<em>ékkentros</em>). If we break down the word, we have that the first part <em>ἐκ</em> means out, while the second part <em>κέντρον</em> means point or center. In other words, "<em>out of the point or center</em>."
Having said that, something or someone eccentric would be an object or person <em>out of the point or center</em>. Center, in this case, means common, normal or ordinary; even convention. Therefore, an eccentric person or object is a person or object out of the ordinary or out of the convention, as expressed in definitions 1 and 2. If we are talking about the sense expressed in definitions 3 or 4, then it would be more literal (<em>center</em> as a point of something).
