Word Substitution is using a single word to substitute a wordy phrase or sentence, making it shorter, more concise, and easier to grasp.

‘Verbatim’ is another term for ‘one-word substitutes.’ ‘One-word substitution’ is a method that involves replacing a word with a context without compromising the meaning of the supplied context.

One-word substitutes are significant because they make English communication far more brief, transparent, and straightforward. Words may be remembered, and more significant concepts can be communicated with a single word.

One word substitution helps to make the word identical to the ruling and has the same meaning as the wordy statement. The easiest method to master this topic is to study its functions by placing them in a phrase or visualizing them through an exciting tale.

The root technique is a simple way to do a one-word replacement. Roots are just the words from which the primary term was developed. Let's look at how to solve these before looking at the One Word Substitutions examples.

Many terms, like Anthropology, are derived from the root word Anthropos, which means "human" ('Anthro' is the prefix here, and 'ology' is the suffix). As a result, anthropology denotes the study of humanity.
