25 Greek and Latin Power Words

The 25 Greek and Latin Power Words combine prefix, base, and suffix morphemes to form over 60,000 words.

Rationale and Purpose

Teachers and students are all about pragmatic tools for teaching Greek and Latin Morphology. 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 high frequency Greek and Latin prefixes, roots, and suffixes.

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. From the five best Greek and Latin word lists cited in these studies, I chose 60 high frequency prefixes, bases, and suffixes. 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 high frequency Greek and Latin prefixes, bases, and meaning-based suffixes) came together. I used the More Words (Now Free Dictionary) 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.
