Which of the following is a basic word part that comes from another language.

Affix
Prefix
Suffix
Root

Affix

The correct answer is "Root." A root is a basic word part that comes from another language, usually Latin or Greek, and carries the core meaning of a word. Contrarily, prefixes, suffixes, and affixes are additional word parts that are added to the root to modify its meaning or create new words.

To determine which of the given options is a basic word part that comes from another language, let's break down each term:

1. Affix: An affix is a word element (prefix, suffix, or infix) that is attached to a base word to create a new word with a different meaning. It can be derived from another language, but it is not a basic word part itself.

2. Prefix: A prefix is an affix that comes before a root word and modifies its meaning. It usually originates from another language and is added to the beginning of a word.

3. Suffix: A suffix is an affix that comes after a root word and modifies its meaning. Similar to prefixes, suffixes often come from other languages and are added to the end of a word.

4. Root: Unlike prefixes and suffixes, a root is not an affix. A root is the primary lexical unit from which words are derived and carries the essential meaning of a word. It can be of native or foreign origin.

Based on the explanations above, the correct answer is "Root." A root is a basic word part that can come from another language and forms the core meaning of a word.
