8. The movie was so funny that we laugh_____ until we cried.

- Root word: *laugh*
- We need an adverb describing how we laughed → laughingly
- But wait — the root is *laugh*, and the suffix is -ly → laughingly?
- However, “laugh” becomes laughed, but here we need an adverb.
- Actually, laugh + -ly = laughly? That’s not a real word.
- Wait — the correct word is laughed (past tense), but the sentence says "we laugh_____" → it’s likely asking for laughed.
- But let's check: “we laugh______ until we cried” → this suggests the verb form should be laughed (past tense).
- So: laughed → suffix -ed

> ✔ Suffix: -ed

> Answer: laughed

Wait! Let’s re-express:
“we laugh_____ until we cried” — the blank follows “laugh”, and the rest of the sentence is in past tense (“cried”), so the verb should be laughed.

✔ Correct answer: laughed
