Key Differences

Both "Augment" and "Supplement" describe processes of addition or enhancement, but they differ in their nuances and typical contexts. These distinctions can shape our understanding and usage of each term in various scenarios.
"Augment" derives from the Latin "augmentum," implying growth or increase. When we use Augment, we focus on enhancing or enlarging an existing entity or concept. For instance, a company might augment its workforce to handle a larger project. Here, the emphasis lies on increasing the size or magnitude of something that's already in place.
In contrast, "Supplement" suggests adding something extra to make up for what's lacking or to provide an additional boost. Supplements often serve to complement or complete. For instance, a student might buy a supplement book to gain extra practice beyond their standard textbook. The implication here is that while the primary source provides most of the necessary information, the supplement offers an extra layer of content or reinforcement.
To sum up, while both terms relate to the idea of addition, "Augment" emphasizes amplification and growth of the existing, whereas "Supplement" stresses the provision of something extra that complements or completes.
