Question

what is a prefix ? what are their types
​

Answer 1

Explanation:

A Prefix is a morpheme or a type of an affix that comes before the base, root or stem word; it comes at the frontal position of the root word. ... A prefix will add meaning to the base word; it can occur in different other words but it cannot stand alone as a word.

The two main types of affixes are prefixes and suffixes. For example, in the word conforming, con- is the prefix and -ing is the suffix, while "form" is the root. For another example, let's examine the root word cred. Thanks to affixes, it can be transformed into incredible with the prefix in- and by the suffix -ible.
