These two engaging poster pages delve into the concept of prefixes, providing a comprehensive overview of their function in English. The first page introduces what a prefix is, explaining how these small additions to the beginning of a root word can significantly alter its meaning. The second page continues the lesson by listing a variety of common prefixes along with their meanings, such as "un-" for "not," "re-" for "again," and "pre-" for "before." Each prefix is accompanied by example words to illustrate their use, making it easier for readers, especially students, to grasp and remember.
