If you want to help your students enhance their vocabulary and reading comprehension effortlessly, consider teaching them Greek and Latin root words! Understanding the meanings of these root words enables students to decipher many unfamiliar terms. Here’s an explanation of how this method works and the most effective root words to introduce to students from grades K-12.
What Are Root Words?
A root word serves as a fundamental building block for constructing larger English words. These root words are often derived from languages like Greek and Latin and typically cannot stand alone. Instead, they are combined with prefixes, suffixes, or other root words to generate entirely new words. Here are a few examples:
- auto (Greek for self) + graph (Greek for write) = autograph (the act of writing your own name)
- bi (prefix meaning two) + cycl (Greek for circle) = bicycle (a two-wheeled vehicle)
- contra (Greek for against or opposite) + dict (speak or say) = contradict (to assert the opposite of something)
- manu (Latin for hand) + fact (Latin for make or do) + ure (suffix meaning the process of) = manufacture (the process of making something, originally by hand)
Interestingly, some words combine both Greek and Latin roots:
- aqua (Latin for water) + phobia (Greek for fear of) = aquaphobia (an intense fear of water)
- dys (Greek for bad) + functio (Latin for to perform) = dysfunction (not functioning correctly)
Modern English is a rich tapestry of languages, influenced significantly by Latin, Greek, French, German, Hindi, Norse, Arabic, and Old English, among others. Greek and Latin roots are among the most prevalent, particularly in academic and scientific vocabulary.
Why Teach Greek and Latin Root Words?
Understanding common Latin and Greek roots greatly aids students in deciphering the meanings of unfamiliar words. When students pair this knowledge with a solid understanding of prefixes and suffixes, they can make sense of many terms, even when taken out of context. This is especially valuable during standardized tests like the SAT.
However, it’s essential to remind students that while root words offer a solid foundation, they can sometimes mislead. For example, “discipline” originates from the Latin term for student (discipulus). In English, “discipline” can refer to an area of study or the concept of self-control, which diverges from the original meaning.
Additionally, root words can be perplexing even when they make sense in their original languages. For instance, salary comes from the Latin root sal, meaning salt, which relates to Roman soldiers being partially paid in salt. Without this context, knowing the root doesn’t provide much clarity.
Despite these occasional confusions, understanding Greek and Latin roots proves beneficial more often than not. Hence, here’s a compilation of some of the most common Greek and Latin root words to share with your students.
