Lesson 5: Joining

In this Grade 5 vocabulary lesson from Vocabulary from Classical Roots Book B, students explore ten words derived from the Latin roots cum (meaning "with" or "together with") and teneo (meaning "to hold" or "to keep"), including terms such as coherent, colloquial, commiserate, pertinacious, and tenacity. The lesson explains how cum transforms into prefixes like co-, col-, com-, con-, and cor- depending on the following consonant, giving students a foundation for decoding unfamiliar words. Part of Chapter 3's focus on joining and connection, this lesson builds both vocabulary depth and classical root recognition skills.
