What is the difference between suffixes and preffixes and give examples for each one?

I agree with specialties answers. Thanks. 

Prefix and Suffix are the set of letters that add to a word and create new word with new meanings. 

Prefixes are added in the beginning as Be

Before

Below

Beneath

Suffixes are added at the end as ship

Friendship

Worship

Lordship

Apologized for the answer, leave the answer for the professionals.

Suffix is added at the end of a word - like -less -  -  - heartless

Prefix is added at the bginning of a word  - like un -  -  - unknown
