Do you know
your Prefix’s
and Suffix’s?
What is a
prefix?
A group of letters usually placed at
the beginning of a root word to
modify or change it’s meaning,
Eg, able becomes unable
happy becomes unhappy
friendly becomes unfriendly
There are many
others, some
examples are…
Irreplaceable
Defrost
Undeniable
Misfortune
Triangle
Bicycle
Semicircle
Imploded
Exploded

Oversight
The word prefix is itself made
up of the stem fix (meaning
attach, in this case),
and the prefix pre- (meaning "before")
The more words you learn, the more
connections you will be able to make
between the prefixes and suffixes.
