Which of the following is the definition of the word prefix? Is it an ethics added at the beginning of the word, route or a basic word part that often comes from Greek or Latin and a fix added to the end of a word route word part added at the beginning, or end of word that changes the words meaning

The correct definition of the word prefix is: a basic word part that often comes from Greek or Latin and is added at the beginning of a word, which changes the word's meaning.

The definition of the word "prefix" is a word part added at the beginning of a word that changes the word's meaning. To arrive at this answer, let's break down the given options:

1. "An ethics added at the beginning of the word" - The word "ethics" refers to moral principles or values and doesn't relate to the definition of a prefix. Therefore, this option is incorrect.

2. "A basic word part that often comes from Greek or Latin" - This is partially correct as prefixes are indeed basic word parts. However, the fact that they often come from Greek or Latin is not a defining characteristic of prefixes. Therefore, this option is not a complete definition.

3. "A fix added to the end of a word route word part added at the beginning or end of the word that changes the word's meaning" - This option seems to be a combination of both a prefix and a suffix (a word part added at the end of a word), which is not a correct definition for a prefix.

So, based on the provided options, the correct definition is that a prefix is a word part added at the beginning of a word that changes the word's meaning.

The definition of the word prefix is: a basic word part that often comes from Greek or Latin and is added at the beginning of a word, which changes the meaning of the word.
