One-word substitution is the process of using one word for a phrase. As the phrase indicates, they are words that replace a group of words or a complete sentence effectively without creating any ambiguity in the meaning of the sentences. Such a replacement makes the sentence structure more lucid. In English, writing precisely and speaking in a single word is essential.

Generally, we speak or write conversationally. But, it is seen that precise words are always understood easily by all. Sometimes, we become verbose, which is optional, and we must talk or speak precisely. This not only makes the language easily comprehendible but also makes it beautiful. On the other hand, we can say that these words are used to effect compression in any writing. For example, in business communication, there are instances when we have to write a lot within the limitation of time and space; these kinds of words prove pretty handy. In the English language, there are a lot of single words for a group of words that can be used effectively to make the writing to the point without losing the meaning of the context.

One word Substitution is one of the integral parts of vocabulary. One easy method of doing a one-word substitution is using the root method. Roots are the words from which the main word has been derived. CRACY, OMNI, CIDE, IBLE, etc., are examples of the root.
