Combining Forms

📋 What it is

Greek combining forms act like roots that love company: -ology = study of, -graphy = writing of, -phile = lover of, -phobia = fear of, -scope = tool to see.

🗣️ Coach says

These are word-building LEGO. "bio + -ology" = the study of life = biology. "tele + -scope" = a far-seeing tool. Snap a topic onto the form and you have named a science or a tool.

🧠 Memory hook

-ology = study of · -graphy = writing of · -phile = lover of · -phobia = fear of.

😂 Giggle

What did "un-" say to the happy word?
"Not so fast — I can flip your whole meaning!"

😲 Whoa!

"Arachnophobia" (fear of spiders) and "philosophy" (love of wisdom) both hide a feeling-part: -phobia = fear, phil- = love.

✅ Quick check: "-ology" means "the study of". What does a "zoologist" study? (zoo = animal)
