What is an acronym?

At first glance, an acronym might look like a combination of initials (or, first letters) of contextually related words. But it’s best to call these types of combinations initialisms rather than acronyms.

Then what is the acronym?

An acronym is a comparatively pronounceable word that might be a combination of initials or a part of a phrase.

One of the most recognizable English acronyms is probably “WWW” which stands for “World Wide Web”.

Types of acronyms

There are two types of acronyms – formal and casual.

Formal acronyms are used in formal documents. Usually, you will notice that formal acronyms are written in capital letters and followed by their full forms in parentheses.
