root - the basic part of a word
example: reCONSTRUCTion
prefix - an addition before the root of a word
example: REconstruction
suffix - an addition at the end of the root of a word
example: reconstructION
The root is what contributes to the basic meaning of a word - prefixes and suffixes serve to narrow down the meaning - who, when, how, in what tense
example: re - again
construct - to build
ion - the action of
So the word RECONSTRUCTION would mean "the action of building again."
Hope that helped! Good luck! :)
P.S. Although you didn't ask for it, the subject is the object in the sentence that is performing the predicate
example: The girl ran to the store.
girl - subject
ran - predicate
It doesn't really have much in common with roots, prefixes and suffixes, all which are similar in function Source(s): Teaching English
