You are probably very familiar with the terms synonym and antonym. Yet there are actually quite a few words in English that incorporate the Greek root word ‘onym’ which means ‘name’. Below are a few of the more common words in which it is found.
A classroom activity could be to divide the students into groups and each group investigates one of these words, compiles a list of examples and then teaches the meaning of the word to the rest of the class.
