What Is Alphabetical Order?
Alphabetical order is a way of arranging words based on the order of the letters in the alphabet. When two or more words start with the same letter, you compare the next letter, and continue until you find a difference. Alphabetical order helps students organize lists, look up words in a dictionary, and sort information quickly.
How to Put Words in Alphabetical Order
Here’s a simple way to alphabetize a list of words:
- Look at the first letter of each word. Sort the words based on A–Z.
- If two words start with the same letter, compare the second letter. Example: apple comes before artist because p comes before r.
- If the first two letters match, compare the third letter, and so on.
- Continue until you find a difference between the words.
