A synonym is a word with the same or similar meaning of another word. An example of this would be the words “buy” and “purchase.” Considering the word synonym, blogger Phil Plait says it well writing, “The antonym of ‘synonym’ is ‘antonym’, and the antonym of ‘antonym’ is ‘synonym’…but ‘synonym’ has no synonym.”’
This is strange because the word alludes to another word with the same definition, yet there is no other word with the same definition as synonym! Just to clarify, there are actually hardly any words that are completely synonyms. Usually, if two words are generally considered synonyms there is always an instance where they could be used differently and destroy the definition. Yet nonetheless, the irony that synonym has no synonym is still hilarious!
