Knowing prefixes or suffixes word parts can greatly help you in decoding words you don’t know.

To understand this concept, let's break it down:

1. Prefixes: These are word parts that are added to the beginning of a word to change its meaning. For example, the prefix "un-" changes the meaning of the base word "happy" to "unhappy."

2. Suffixes: These are word parts that are added to the end of a word to change its meaning or function. For example, the suffix "-able" added to the base word "read" creates the word "readable."

3. Base Words: These are the core words to which prefixes and suffixes can be added. They are the foundational words from which other words are derived. For example, the base word "employ" can have the prefix "re-" added to form "reemploy."

By learning common prefixes and suffixes, you can decipher the meaning of unfamiliar words. For example, if you encounter the word "unhappiness," you can understand its meaning by recognizing the prefix "un-" indicating negation and the suffix "-ness" indicating a state or quality.

Understanding word parts can be useful for improving your vocabulary and comprehension. There are many resources available, such as vocabulary lists, flashcards, and online courses, that can help you learn and practice different word parts.
