Like root words, many prefixes in
English come from Latin or Greek.
In fact, more than half of the words
we use each day come to us from
Latin or Greek.

Words can be broken
into smaller parts.
These word parts
include:
• Roots
• Prefixes
• Suffixes

When you see a word made up
of multiple word parts:
• Look at each part of the word.
• Combine the individual meanings
to determine the meaning of the
entire word.

You could try to memorize the meaning
of each new word and have one new
word in your vocabulary.
Or you can learn how to figure out
meanings of unfamiliar words and for the rest of your life
be able to understand most
words you see and hear.

Improving your vocabulary also
improves and increases your

Prefixes are at the beginning
of a word.
A suffix is a word part that’s placed
at the end of a word to change its

They cannot stand alone.

Prefixes –
tend to affect the
meaning of a word.
Suffixes –
usually determine the
part of speech.

When a prefix is added to a base
word or a root, the new word is a
combination of –
• the meaning of the prefix
• and the meaning of the
base word or root.

When a suffix is added to a word,
the spelling of the original word
usually stays the same.
Examples:
nine + ty = ninety
hope + ful + hopeful
awe + some = awesome
care + less = careless
RPDP Secondary Literacy
When a word ends in silent –e:
• Usually drop the -e if you are adding
a suffix that begins with a vowel.
• But keep the -e when you are adding
a suffix that begins with a consonant.
Examples:
love + able = lovable
love + less = loveless
RPDP Secondary Literacy
When a word ends in a -y preceded
by a vowel, just add the suffix.
Example: gray + est = grayest
When a word ends in a consonant,
double the final consonant before a
suffix that begins with a vowel only if
the word:
• has only one syllable or is accented
on the last syllable and
• ends in a single consonant
preceded by a single vowel.
