Today, I am going to discuss the definition of root word. Roots are base
words to which other characters or letters like prefixes and suffixes are attached.
Roots constantly mean the same thing and are the base for related words.
I will give the two origin of root words, the Latin and Greek that mostly
used in Science and English and I will give you a lot of examples of it.

There are many root words that can be used on their own or as parts of other common
words in the English language. These are also referred to as base words. Here are the examples.
• Act - means to move or do. Acting
• Arbor - means tree. Arboreal
• Crypt - menas to hide. Cryptic
• Dress - means clothing. Undress
• Ego - mean "I". Egotist
On the other hand, some root words aren’t full words but form the basis of
many different words. Here are the examples.

• Corp - means body. Corporate
• Deca - means ten. Decade
