Understanding Roots and Affixes


Affixes include prefixes and suffixes and
combined with root words and base words.
They can quickly multiply the number of
words you know.
It is more efficient to memorize the meaning
of these word parts than to memorize
definitions that you will end up forgetting in a
few days anyway.
Word Roots (can’t stand on own)



A word’s root is the part of the word that
carries the most meaning.
Latin and Greek roots are extremely
important in unlocking vocabulary you never
knew before.
For example if you know that there are two
Latin words that mean “light”- luc and lumyou can at least begin to figure out the words
on the following slide.

Luminous

radiating or reflecting light
Lucid

easily understood, clear perception or
understanding
Translucent

clear, easily understandable
Illuminate

knowledge

Affixes: prefixes and suffixes
It might have helped you on some of these
words to know some affixes for example:

-ous is a suffix that creates an adjective

Trans- means across or through

Il- means not
Prefixes



Prefixes can be added to the beginnings of
many words to change the word’s meaning.
For example, the prefix un- gives the
opposite meaning to any word it is added to.
Some prefixes have more than one meaning
but having these memorized will enable your
vocabulary to transcend its normal range.
Suffixes



A suffix is placed at the end of a word or part
of a word.
When you add suffixes you often change the
word’s function (part of speech) as well as its
meaning.
Check out the example on the next slide.
