Here's why:
* Etymology: Etymology is the study of the origin and history of words.
* Root: In etymology, a root is the basic form of a word, stripped of any prefixes or suffixes. It carries the core meaning of the word.
* Analogy to Languages: Just as languages can be traced back to ancestral roots, words can be traced back to their etymological roots.
Example:
* The word "unbreakable" has the root "break".
* The word "prehistoric" has the root "history".
By understanding the root of a word, we can often gain a deeper understanding of its meaning and its relationship to other words.
