Tips to Identify Root Words in a Word

While learning English grammar, understanding root words is very important because it makes reading, writing, and vocabulary easy. When you know how to find root words in English, you can understand many new words quickly without memorising every word.

1. Look for Prefixes and Suffixes

Many words have prefixes (letters at the start) and suffixes (letters at the end). Removing them can show the root word. For example: in unhappy, “un-” is the prefix, and happy is the root.

2. Remove Extra Letters to See the Base

Sometimes, taking away the extra parts of a word helps find the main meaning. For example, in transportation, removing “trans-” and “-ation” leaves port, which means “to carry.”

3. Use Context to Find the Root

Some words may look like they have a prefix, but they don’t. Reading the word in the sentence can show the true root. For example, in submit, “sub-” is not extra; the whole word submit is the root.

4. Learn Common Greek and Latin Roots

Many English words come from Greek or Latin roots. Knowing them helps you understand word meaning. For example, Graph means “write”. So, an autograph means self-written.

5. Practice On a Regular Basis

The more you read and notice roots in words, the easier it becomes for you to identify root words. Practice helps you understand words faster and improve your vocabulary.

Root Words With Prefixes and Suffixes

We can combine root words with prefixes and suffixes to make new words. Prefixes are letters we add at the beginning of a word, and suffixes are letters added at the end. They can change the meaning of the word or the type of word.

For example, prefixes like dis- and un- change the meaning to the opposite. Suffixes can change the word type. Check the list of root words with prefixes and suffixes:

Root Words With Prefixes and Suffixes

Type

Prefix/Suffix

Example

Prefix

dis-

disbelief (from belief)

Prefix

un-

uncertain (from certain)

Prefix

re-

revisit (from visit)

Prefix

pre-

preview (from view)

Suffix

-ion

action (from act)

Suffix

-able/-ible

readable (from read)

Suffix

-ly

quickly (from quick)

Suffix

-er/-or

teacher (from teach)

Suffix

-ness

kindness (from kind)

Suffix

-ful

joyful (from joy)

Sometimes, root words can act like affixes too. For example, astro means “star.” Alone, it is not a word, but it can make new words like astronomy or astronaut. This shows how prefixes and suffixes can change words in many ways.
