Grade 4 students in Vocabulary from Classical Roots Book A explore the Latin and Greek roots PAN, OMNIS, HOLOS, TOTUS, and CLAUDO, all meaning "all," "whole," or "close," to build understanding of words like omnipotent, omnivorous, panacea, pandemonium, totalitarian, holocaust, cloister, preclude, and recluse. Students learn how these classical roots connect to meaning across a range of vocabulary words used in historical, scientific, and everyday contexts. The lesson develops both word recognition skills and deeper comprehension of how root words shape the English language.
Section 1
The Concept of 'All' (PAN)

| Word | Definition |
|---|---|
| pandemonium | (n.) wild and noisy chaos |
| panacea | (n.) a cure for all problems |
Section 2
The Power of 'All' (OMNIS)
Now, let's look at another root for "all," the Latin root OMNIS. These words describe being all-powerful, all-present, and eating it all!

| omnipotent | (adj.) having all power |
| omnipresent | (adj.) present everywhere |

Section 4
