Some of the prefixes and suffixes to be added to the words are:
<h3>What is a Prefix?</h3>
This refers to the addition of a letter(s) to a word at the beginning in order to change its meaning.
Hence, we can see that a suffix is similar to a prefix, but the only difference is that a suffix is the addition of the letter(s) at the end of a given word.
A good example is:
- Base word: Decision
- Prefix: Indecision.
- Base word: Careless
- Suffix: Carelessness
Please note that your question is incomplete, so I gave you a general overview to give you a better understanding of the concept.
