Hi everyone 👋 He had a very boy ... smile a. -ous b. -ish c. -ary He had to sell his business because it wasn't profit... a. -ful b. -able c. -like d. -ward How do I know the correct suffix? Is there any explanation for this? because I only have "suffixes can be added to nouns to form adjectives" in my book Thank you 🙌
