What is a Synonym?

What is a synonym? A synonym is a word or expression that has the same or almost the same meaning as another word or expression. In English, a language known for its enormous vocabulary, most words have synonyms. For example, the word “enormous” has many synonyms: Huge, massive, giant, immense, and the list goes on. The word “synonym” is a composite of two Greek words: The prefix “syn” means “together” and “onym” is “name.” Synonyms — together naming the same thing.

Synonym Tests

Synonym tests ask you to select a word’s synonym from a list of choices, or to read a sentence and decide which word is similar in meaning to the underlined word in the sentence. For example: “John thought he was lucky to have good friends.” Pick the synonym for “lucky” from the choices “smart,” “fortunate,” and “sophisticated.” Think twice about words that make sense in the sentence—these choices may not have the same or similar meaning as the underlined word. Think of the letter ‘S’ in synonym as standing for “same” or “similar,” and you’ll keep on track. “Fortunate” is the answer.
