Prefix exercise 2
PRE
PRE means BEFORE
This is a common prefix that can be connected to fairly common words as well as more challenging ones. Both are included in this list.
Note that 'before' can have to do with time *or* space. To "predict" is say something will happen before it does; but to "present" something to you is to place it before you in space.
"Pre" can have other meanings than "before," though (as in the words prevail, pretend, prehensile, and prevaricate).

Prefix exercise 3
UN
UN means NOT
There are several prefixes that mean "not" in one way or another. However, they are different, so sometimes you will have two different "not" suffixes in front of the same ending, and the two words will mean different things.
An "unarmed" man does not have a weapon. If the man is "Disarmed," then there was a weapon but it was taken away (and 'disarming' has several meanings). "Uninterested" means you "do not have the mind or feelings engaged." You're not involved; you don't care. "Disinterested," however, has come to mean "not having a selfish motive or interest." A "disinterested" person is good to help settle an argument.
Un- words are usually verbs (unplug or untie) or adjectives (untidy, unbreakable)
