What is the root word, prefix and suffix of these?

Question

1) interrupt
2) scribble
3) despise

Answer 1

(No suffixes here)

1) prefix =inter-
root =ruptus
* from Latin interruptus, past participle of interrumpere, to break off : inter-, inter- + rumpere, to break (compare "rupture")
http://www.thefreedictionary.com/interrupt

2) root only (no prefix or suffix)
* late ME scribblen (v.) < ML scribillare to scribble, deriv. of L scribere to write
http://dictionary.reference.com/browse/scribble

3) prefix = de-
root = spise < specere
* from O.Fr. despis-, stem of despire, from L. despicere "look down on, scorn," from de- "down" + specere "look at"

Note the three web sites I drew from. These are excellent places for you to look up the answers to such questions. (You might also pick up a dictionary. The American Heritage Dictionary of the English Langauge is my favorite for this sort of thing, but many others will do.)

Answer 2

Inter Root Word

Answer 3

1) in--
3) de--
are prefixes.
2)--le
is the suffix.
What's left is the root word. To help you remember the difference between "prefix" and "suffix", remember that the "PRE" in "prefix" means "first" or "early," so it's added onto the beginning of a word.
