In terms of language, what does the 'root' of a word typically reflect?

The 'root' of a word serves as the foundational part that conveys the primary meaning, before any prefixes or suffixes are added. Understanding the root allows readers and learners to grasp the basic concept or idea that the word represents. For instance, in the word 'unhappiness,' the root 'happy' holds the central meaning, while the affixes (the prefix 'un-' and the suffix '-ness') modify this meaning but do not change the root's core significance. This fundamental understanding is crucial in expanding vocabulary, as it can help individuals deduce meanings of unfamiliar words by recognizing their roots and how different affixes interact with them.
