One-word substitution is a technique in which a single word is used to substitute a long-phrase in order to simplify the sentence structure. This also makes work less complicated and more succinct.


One-word substitution is a test in which a single word is used to substitute a long phrase or a sentence in order to simplify the sentence structure making it shorter, concise and clearer to understand. As a result, the word becomes synonymous with the sentence, conveying the same meaning as the lengthy sentence. 

For example, if you have a statement that says "He does not believe in God," you can replace it with "He is an atheist." Although the meaning is the same, the statement is shorter. This gives the writing a layer of in-depth meaning while still keeping it concise. 

Purpose of One-Word Substitutions 

Highlight: One-word substitutes are important because they make English communication far more brief, transparent, and simple. Words can be remembered and larger meanings can be communicated with a single word. Sentences become more precise and reduce complexity with one-word substitutions. 

Now, let us look at how to solve One-Word substitutes.  

These can be solved by identifying the 'root word' or core meaning, followed by determining the prefix and suffix. 

Many words, like Anthropology, are derived from the root word anthrpos, meaning "human" (the prefix "anthro" and the suffix "ology"). As a result, anthropology refers to the study of humanity. To master understanding root words, you must be knowledgeable with the etymology and linguistics of words. 

In science, the most common suffix is 'ology,' which means "a branch of knowledge." (For instance, psychology and biology.) 

The suffix "cracy" is derived from the Greek word "kratia," which signifies "rule or governance." (Autocracy and Democracy are two examples.)
