the best way to locate a suffix is to look for a word part that includes \pre\, \a\, or \en\ for example. shows the words central meaning. is added to the end of the word root. is added to the beginning of a word root.

Explanation:

A suffix is a word - part added to the end of a word root. For example, in the word "happiness", "ness" is the suffix added to the root "happy". The option "includes 'pre', 'a', or 'en' for example" is incorrect as these are prefixes. The option "shows the word's central meaning" refers to the root of the word. The option "is added to the beginning of a word root" also refers to a prefix.

Answer:

is added to the end of the word root.
