Negation & Direction
📋 What it is
Some prefixes flip meaning or point a direction: un-/dis-/non- = not, re- = again/back, sub- = under, trans- = across, pre- = before.
🗣️ Coach says
These prefixes are steering wheels. "un-" reverses a word (do → undo), "re-" repeats it (play → replay), "trans-" carries it across (atlantic → transatlantic). Small part, big turn.
🧠 Memory hook
un/dis = not · re = again · sub = under · trans = across · pre = before.
😂 Giggle
Why did "chrono" always run late?
It could never stop thinking about time!
😲 Whoa!
"Submarine" is literally "under-sea" (sub + marine) — the prefix tells you exactly where it goes.
✅ Quick check: What does the prefix "re-" add to the word "build" in "rebuild"?
Say your answer out loud first — then reveal.
It means "again" — to rebuild is to build again.
A direction/negation prefix changes a root without you relearning the root.
🧪 Try it! (2 minutes)
Add "un-", "re-", and "pre-" to "view" and say what each new word means.
