What Are Abbreviations, Initialisms, and Acronyms
Here’s further detail
Abbreviation
An abbreviation is a shortened form of a word or phrase created by omitting letters, syllables, or words. It helps save space and time in writing and speaking.
Key Features
- Can be made from parts of a word or multiple words.
