What is an affix?

An affix is correctly identified as a letter or group of letters added to a base word. This practice plays a significant role in language, as affixes can alter the meaning of the base word or create a different grammatical form. For instance, the prefix "un-" can be added to the word "happy" to create "unhappy," changing its meaning to the opposite. Similarly, suffixes like "-ing" can be added to verbs to indicate an ongoing action, as in "running."

Understanding affixes is crucial in multi-sensory structured language education, as it enhances vocabulary development and spelling proficiency. Students learn to decode words and grasp their meanings more effectively, which is vital for reading comprehension and language acquisition.
