| derivation |
A derivation is a statement of the origin of a word. Words originated somewhere and meant something originally. Through the ages they have sometimes become altered in meaning. Knowing the Derivations helps greatly to get the full understanding of words. When the student looks up words in the dictionary he has to read the small-print that explains where the word originally came from.
