What Are Root Words?
A root word is the primary lexical unit, or most basic part of a word. It contains the essential meaning. We add prefixes and suffixes to roots, to add to the basic meaning of the root.
Let’s look at the root word nature, which refers to the living, material word. When we remove the final e, and attach ‘al’ to the end of the noun, we turn it into the adjective natural. If we then add the prefix ‘un’ we have unnatural, meaning not in accordance with what can and should occur in nature.
We can also put two root words together, to create a new word. The root bio means ‘life’, and logy means ‘the study of’. When we put them together, we get biology, the study of life.
