English Grammar Prefixes and Suffixes Worksheet for Grade 4
A strong vocabulary and a clear understanding of word formation help students become confident readers and writers. In Grade 4, learning how prefixes and suffixes change the meaning of words is an important step in building grammar skills. This English grammar worksheet on Prefixes & Suffixes (un-, dis-, -ful, -ness) helps students recognize how words can be modified and used correctly in sentences. By practicing with different types of questions, students strengthen their ability to identify prefixes and suffixes and use them in everyday language.
What Is the Topic?
Prefixes and suffixes are word parts that are added to a base word to change its meaning. A prefix is added at the beginning of a word, while a suffix is added at the end.
In this English grammar worksheet, students learn how common prefixes like un- and dis- and suffixes like -ful and -ness modify words. These additions can create new meanings or change the function of a word in a sentence.
For example, the prefix “un-” can change a word to its opposite meaning, while the suffix “-ful” often shows that something is full of a quality. By practicing with these word parts, students learn how to recognize patterns in English vocabulary and apply them correctly.
Through activities such as matching, sorting, filling in blanks, multiple-choice questions, and sentence rewriting, Grade 4 students develop a deeper understanding of how prefixes and suffixes work in everyday language.
