Answer:
Etymology
Step-by-step explanation:
When you look up a word in a dictionary, you will find many things in addition to the definition. An unabridged dictionary will have the most information (as opposed to an abridged, which would be condensed with regard to the amount of information available). It will contain, generally, the part of speech the word is (such as noun, verb, etc.), antonyms (words that have an opposite meaning), synonyms (words that have similar meaning), and etymology (which is the word’s origin and history such as from what original language the word originates).
