Which of the following is a word root? (1 point)

• an affix added at the beginning of a word root
• an affix added to the end of a word root
• a basic word part that often comes from Greek or Latin
• a word part added at the beginning or end of a word root that changes the word's meaning

• a basic word part that often comes from Greek or Latin

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

The correct answer is: "a basic word part that often comes from Greek or Latin."

To determine which option is a word root, we need to understand the meaning of each choice:

1. An affix added at the beginning of a word root: This is called a prefix, not a word root. Prefixes are added at the beginning of a word to modify its meaning.

2. An affix added to the end of a word root: This is called a suffix, not a word root. Suffixes are added at the end of a word to modify its meaning.

3. A basic word part that often comes from Greek or Latin: This is the definition of a word root. Word roots are the core or base part of a word that carries the main meaning. They are often derived from Greek or Latin languages.

4. A word part added at the beginning or end of a word root that changes the word's meaning: This is a combination of a word root and an affix (either a prefix or a suffix). While it does modify the meaning of the word, it is not a word root on its own.

Therefore, option 3, "a basic word part that often comes from Greek or Latin," is the word root among the given choices.
