This document discusses how words are formed through roots, affixes, and derivation. It defines roots and base words, and explains that roots can form new words when affixes like prefixes and suffixes are added. Prefixes come before the root or base, while suffixes come after. Derivation changes the word class by adding affixes, like changing an adjective to a noun with the "-ness" suffix. Inflection changes grammatical properties like tense without changing the word class. Common prefixes and suffixes are provided as examples of how they can modify roots and bases to derive new words.
2. Root or base word
A root is a word part that comes from another language, such as Greek
or Latin. A root word may or may not have a meaning. It can not be
reduced to a smaller part.
e.g. speak solve talk dis- -able -ness
A base word is the form of a word to which prefixes and suffixes can be
added to create new words. It has a meaning on its own, and it is a
word that can stand on its own.

instruction instructor reinstruct
3. Differences of root and base word
New words can be formed using root words and base words by
adding suffixes or prefixes, and several affixes can be added to root
words to have a meaning.
A root word is the basic linguistic unit, and it is the original form of a
word while a base word is a word in its simplest form.
E.g. They repainted the old car.
re + paint + ed
prefix base suffix
4. Affixes
An affix is a word part that can be attached to either a root or a
base word to create a new word.
Affixes can be divided into two categories: prefixes (appear at
the beginning of words) and suffixes (appear at the end of
words).
Common Prefixes Common Suffixes
Bi- two -al adjectival suffix
Anti- against -fy verb suffix
Inter- between -ic adjectival suffix
Pre- before -ion noun suffix
Super- above -ism noun suffix
Trans- across -ize verb suffix
Dis- not -ous adjectival suffix
5. Apply
For example one could analyze the word intangible, using the chart
shown previously.
First break the word into its parts:
Prefix Root suffix English word
In- + tang + -ible = intangible
Tang is a latin root meaning touch
In- is a prefix meaning not
-ible is a suffix meaning able to
6. Derivation and inflection
Derivation: by adding a prefix or suffix, such as -ness or un-. For
example, happiness and unhappy derive from the base word happy.
Inflection: refers to modification of a word to express
different grammatical categories such
as tense, case, voice, aspect, person, number, gender, and mood.
