If you’re looking for an easy way to boost your students’ vocabulary and reading comprehension, teach them Greek and Latin root words! Once they know the meanings of the root words, they can figure out the definitions of so many other words. Here’s why it works and the best root words to teach kids in grades K-12.
What are root words?
A root word is a basic building block used to create larger English words. Root words come from other languages, often Greek and Latin, and can’t usually stand on their own. Instead, they’re combined with prefixes, suffixes, and/or other root words to create a whole new word. Take a look at these examples:
- auto (Greek for self) + graph (Greek for write) = autograph (to write your own name)
- bi (prefix meaning two) + cycl (Greek for circle) = bicycle (two-wheeled vehicle)
- contra (Greek for against or opposite) + dict (speak or say) = contradict (to say the opposite of something is true)
- 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)
You’ll even find examples that combine both Greek and Latin root words in a single word!
- aqua (Latin for water) + phobia (Greek for fear of) = aquaphobia (fear of water)
- dys (Greek for bad) + functio (Latin for to perform) = dysfunction (not performing correctly)
Modern English is a real hodgepodge of a language, influenced by Latin, Greek, French, German, Hindi, Norse, Arabic, and Old English, just to name a few. Greek and Latin root words are among the most common, especially when it comes to words used in academia or science.
Why teach Greek and Latin root words?
Knowing the definitions of common Latin and Greek roots gives students a real boost when it comes to working out the meanings of unknown words. When you combine this information with a good working knowledge of prefixes and suffixes, it’s easy to make sense of many words, even out of context. (This can be very helpful on standardized tests like the SAT.)
It’s important to make sure your students know that while root words can be a good starting point, they can also be misleading sometimes. “Discipline” comes from the Latin word for student or learner (discipulus). In English, discipline can mean an area of study, which is related to the Latin root. But it can also mean self-control, or a form of punishment, meanings that the root word don’t make clear.
In other cases, the root word is downright confusing, though it made sense in other languages. For instance, salary comes from the Latin root sal, which means salt. If you know that Roman soldiers were partly paid in salt, it makes sense. But otherwise, knowing that root doesn’t really help.
That being said, knowing Greek and Latin roots is helpful more often that not. That’s why it’s worth sharing this list of the most common Greek and Latin root words with your students.
