Synonyms and keywords
Synonyms are different words with identical or very similar meanings. Words that are synonyms are said to be synonymous, and the state of being a synonym is called synonymy.
The word comes from Ancient Greek syn (Template:Polytonic) ("with") and onoma (Template:Polytonic) ("name").
For example, the words car and automobile are synonyms. Similarly, if we talk about a long time or an extended time, long and extended become synonyms.
