The Prefixes ..

For a start, A prefix is a group of letters that we put at the beginning of a word and it changes the word's meaning
:The most common prefixes are
"Anti"
.which means against
.E.G: this is an anti-water paint
"co-"
.which means with or a part of
.E.G: This is my co-owner that uses my account. > here it means my backup owner
"Un-"
.also means against and it usually comes to make the word negative
.E.G: The girl is uncool
"pre-"
.which means before
.E.G: I already pre-ordered the sweater online
"dis"
.which means away or a part
!E.G: My necklace disappeared today, I don't know where I threw it

and a lot of other prefixes, you can go search in Google if you want ..
I hope that simple explanation helps anyone in whatever you need it in!
!Good Luck
