Suffix vs. Prefix: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
A suffix is an addition to the end of a word (e.g., "-ness" in "happiness"), while a prefix is added to the beginning (e.g., "un-" in "unlikely").
Key Differences
A suffix is a letter or group of letters added to the end of a word to modify its meaning or create a new word, often changing the word class. In contrast, a prefix is attached to the beginning of a word, altering its meaning without usually changing its word class.

Suffixes often change the grammatical function of a word, such as turning a verb into a noun (e.g., "run" to "runner") or an adjective into a noun (e.g., "happy" to "happiness"). Prefixes, however, typically modify the meaning of a word by adding a negation, intensity, or other nuances (e.g., "happy" to "unhappy").

Common suffixes include "-ful" (as in "hopeful"), "-ness" (as in "sadness"), and "-ly" (as in "quickly"). Common prefixes include "un-" (as in "undo"), "re-" (as in "redo"), and "dis-" (as in "disagree").

Many suffixes can change the word class; for example, "-tion" changes verbs to nouns (e.g., "inform" to "information"). Prefixes usually retain the original word class; for instance, "un-" added to an adjective still forms an adjective ("happy" to "unhappy").
