Thank you Writeacher.

You're very welcome!

Let's go through your answers to see if they are correct:

Nouns: Stanley, lizard, toothbrush - Correct!

Adjectives: sweet, fresh onions - "sweet" and "fresh" are correct adjectives, but "onions" is a noun. So the answer here should be "sweet" and "fresh."

Gold - This is a noun, not an adjective. So the correct answer should be "gold" as a noun.

Small flowered - Yes, "small flowered" is a correct adjective.

Leaky - Yes, "leaky" is a correct adjective.

Adverbs: think clearly, smiled sheepishly, feet tangled, shook violently, died laughing - All of these are correct adverbs!

Verbs: slams, think, shook, wake, dig - All of these are correct verbs!

Overall, you did a good job finding the nouns, adjectives, adverbs, and verbs from the book. Just a small correction for the adjectives, where "onions" should be replaced with "gold." Keep up the good work!
