Level 3 Unit 3 Lesson10: Something Irresistible

By the end of this lesson, you will be able to:

  • Use the prefixes «ir-», «il-», and «im-».
  • Use the suffix –er to say who says something.

Reminder:

Prefixes and suffixes are letters that we add to the beginning or end of another word (root word).

We add prefixes to the beginning of an existing word to create a new word with a different meaning.

We add suffixes to the end of an existing word. Suffixes often change a word from one word class to another; for example, a verb can become an adjective, a noun can become an adjective, or a verb can become a noun.
