Final answer:
Not all words contain both a prefix and a suffix; some may have only one or none.
Explanation:
Words do not always have both a prefix and a suffix. Some words may have only a prefix, only a suffix, or none at all. For instance, 'happy' has no affixes, while 'unhappily' has both a prefix ('un-') and a suffix ('-ly'). Recognizing common prefixes and suffixes can aid in understanding and decoding unfamiliar words.
