Question

Does beginning have a suffix

Answer 1

A suffix is something that is added onto a word on the end. In this case it's the 'ing' So yes, beginning has a suffix.

For future reference a prefix is something that goes at the beginning.

Word example: Indescribable.

'In' is the prefix, describe is the root word, and 'able' is the suffix.

Answer 2

Yes because "ing" is a suffix that is at the end of the word. Without it, you just get beginn/begin!
