Student creating detailed Italian language outlines.

Understanding prefixes and suffixes is essential for anyone looking to expand their English vocabulary. A prefix is a group of letters added to the beginning of a word to alter its meaning, while a suffix is a group of letters added to the end of a word to change its grammatical function or overall meaning. Together, they are known as affixes. Recognizing these can help learners deduce the meanings of new vocabulary and assist in their correct usage.
