What is a word root?

A word root is indeed the main part of a word, serving as its core meaning. This root forms the basis upon which additional elements, such as prefixes and suffixes, can be attached to create related terms. For example, in the word "biological," the root "bio" refers to life, which gives insight into the word's meaning related to living organisms. Understanding word roots is crucial in health science, as many medical terms are built from Greek and Latin roots that convey specific meanings. This foundational knowledge allows for better comprehension and retention of complex terminology encountered in the field.
