One word substitution is a word used to describe the phrase with a single word that expresses the same meaning. It is often used in writing and language instruction as a way to improve concision and clarity.

It is a technique where a single word is used to replace a phrase or sentence that has a similar meaning. This can be done to make writing or speech more concise and efficient. 

For Example, using the word “feline” instead of “cat-like,” or “vegetarian” instead of “someone who does not eat meat.” This technique can also be used to replace technical or complex terms with simpler, more commonly understood words.
