With the increased use of electronic communication, the use of abbreviations has increased.

NVM is an acronym for “never mind” which is most widely used in informal communication. The term NVM has been a part of our internet language for a very long time. It is mostly used while texting rather than speaking. Instead of writing the whole phrase, most people prefer writing it as nvm or NVM. The term can be written in either all capital or small letters.

Examples:

-Nvm, I have already found it.

-I’m really sorry. Nvm, I didn’t mean it actually.

-Nvm, I forgot that it was already cleared a few days back.

-Sorry, nvm, I meant to send the meme to someone else.
