15 Power Words to Teach Greek and Latin Word Parts

15 Power Words

A number of years ago, I developed a list of 15 Power Words to Teach Greek and Latin Prefixes and Roots, which combined many of the most commonly used prefixes and roots. I estimated that these word parts were found in at least 15,000 words in our unabridged English dictionaries. Elementary teachers found this list to be a helpful resource to narrow down which word parts to teach, and which ones not to teach. I included the 15 Power Words in my popular grades 4, 5, 6, 7, and 8 Common Core Vocabulary Toolkits and featured this list in numerous articles on this Pennington Publishing Blog. Yes, you are welcome to download the 15 Power Words for free. I would especially recommend the words on this list and the 32 high frequency prefixes and roots found within the 15 Power Words for grades 2–5 students.

Research Background

As I began research on reading comprehension for my upcoming 2019 book, How to Improve Your Reading Comprehension, I found an additional research study [Wei, Z., 2011] on high frequency productive Greek and Latin roots, which narrowed down previous research-based lists. Plus, Wei’s dual approach to both utility and frequency was useful for my target audience: English-language arts and reading intervention teachers and their students.

Rationale and Purpose

Teachers and students are all about pragmatic tools. High utility and high frequency vocabulary words give them the most bang for the buck. Teachers want to teach both the high utility Tier 2 academic vocabulary and the the high frequency Greek and Latin prefixes, roots, and suffixes. My 25 Greek and Latin Power Words provide both. I decided to update and expand my 15 Power Words model to include both the highest utility and the highest frequency Greek and Latin prefixes, roots, and suffixes for not only elementary, but also middle school, high school, college, and post-college students of our English language. I wound up with the 25 Greek and Latin Power Words.

Methodology

I compared the results from the most recent and well-regarded vocabulary research studies on high frequency Greek and Latin word parts, including the additional study by Dr. Zheng Wei, mentioned above. From the five best Greek and Latin word lists cited in these studies, I chose the 60 highest frequency prefixes, roots, and suffixes. I then spent far too many hours trying to replicate my original 15 Power Words model, which has 32 high frequency prefixes and roots, with my now expanded list of 60 word parts. The chunking of two or three word parts into one academic language word applies time-tested association memory research. We simply remember linked items better than we remember items in isolation.

Results: The 25 Greek and Latin Power Words

At last, the list of 25 Greek and Latin Power Words (including all 60 highest frequency Greek and Latin prefixes, roots, and meaning-based suffixes) came together. I used the More Words site to check the number of words in which each of these 60 word parts appear in the English language. The results were staggering: The 60 word parts are found in over 60,000 words, including their inflections (a conservative total). With our English lexicon of about 600,000 words, these 60 word parts constitute 10% of the words in our language. With a middle school student’s average vocabulary of 25,000 words and a college-educated adult’s average vocabulary of 60,000 words, the 25 Greek and Latin Power Words can have a significant impact on improving reading vocabulary for all ages.
