The root of a word carries the most significant content of the word’s meaning. Different words are formed by adding prefixes or suffixes to the root;
Root: for example, “cred” means “believe” and from there we get “credible”, “credit”, “credence”, etc.;
Prefix: for example, “cent(i)” means “hundred”. We have “centimeter”, “century”, “centennial”, etc.;
Suffix: for example, “-able” or “-ible” means “capable of doing”. We have “preventable”, “adaptable”, “predictable”, “credible”, etc.;
