Chapter 2: Definition of Terms

 

  1. Etymology – The study of word origins or word history. For example the words “royal” and “regal” both come from the Latin word “regalis”, which means “kingly”. Further, the word

“student” is derived from the old French term estudiant, “one who studies” and  influenced by the Latin term studere, “to study”.

 

  1. Context clues – Signal words, devices, or sentences that give clues to the meaning of an unknown word. The context of words, or how they are used in sentences, will determine their word  meaning.

      

  Study the following examples which use the word “light”:

 

A.) The books are light. I can carry them easily. (light in this sentence means “not heavy”)

B.)  Donna saw the light and, therefore, was able to solve the algebra problem. (“to understand”).

C.)  To dispel the darkness, Min turned on the light in the living room. ( “device used to illuminate”)
