Why etymology helps you remember words
Most vocabulary tools give you a word and a definition to memorize by brute force. Research on vocabulary acquisition shows that breaking a word into its prefix, root, and suffix — and connecting it to a vivid mental image (a mnemonic) — dramatically improves long-term recall compared to rote memorization.
For example, knowing that "benevolent" comes from Latin "bene" (good) and "volens" (wishing) doesn't just help you remember this one word — it also unlocks related words like "benefit," "benefactor," and "beneficial," all built from the same root.
