A word part added at the beginning or end of a word root that changes the word's meaning is called a prefix or suffix.

An affix added to the end of a word root is called a suffix.

An affix added at the beginning of a word root is called a prefix.

A basic word part that often comes from Greek or Latin is called a root or base word.

There are four types of word parts that are commonly used in creating and changing the meaning of words:

1. A prefix: This is a word part added at the beginning of a word root that changes the word's meaning. For example, in the word "unhappy," "un-" is a prefix that negates the meaning of "happy."

2. A suffix: This is an affix added to the end of a word root. Suffixes serve various purposes, including indicating verb tense, pluralization, or changing the part of speech of a word. For example, in the word "careful," "-ful" is a suffix that means "full of" or "characterized by."

3. A combining form: A combining form is a word part that often comes from Greek or Latin and is used as a base for creating new words. These combining forms are usually attached to prefixes or suffixes to build complex words. For example, the combining form "bio-" from the Greek word "bios" means "life" and is used in words like "biology" and "biography."

4. A word root: A word root is a basic word part that carries the core meaning of a word. It is usually a standalone word or a base to which prefixes or suffixes can be attached. For example, in the word "helpful," "help" is the word root that carries the central meaning of "assisting" or "aiding."

By using these different word parts, complex words can be created and their meanings modified.

To identify the word parts mentioned in the question, we need to understand the definition of each term:

1. Word part added at the beginning or end of a word root that changes the word’s meaning: This is called a prefix or a suffix.

- A prefix is an affix added to the beginning of a word root, altering its meaning. For example, in the word "unhappy," the prefix "un-" changes the meaning of "happy" from positive to negative.

- A suffix, on the other hand, is an affix added to the end of a word root, modifying its meaning. In the word "happiness," the suffix "-ness" turns the adjective "happy" into a noun representing the state or quality of being happy.

2. An affix added to the end of a word root: This refers to a suffix, as explained above.

3. An affix added at the beginning of a word root: This is a prefix, as mentioned earlier.

4. A basic word part that often comes from Greek or Latin: These are called roots or base words. Root words are the core building blocks of words and carry the primary meaning. Many root words have their origins in ancient Greek or Latin. For instance, the Latin root "bi-" means "two" (e.g., bicycle, bilateral) and the Greek root "tele-" means "distant" (e.g., telephone, telepathy).

Remember, prefixes and suffixes modify the meaning of root words, whereas root words themselves are the foundation of words and often originate from Greek or Latin.
