BTW Meaning : What is it? Where to use it?

[Jasongonzales]

Can anyone explain what 'BTW' means and when it’s best to use it? I see it a lot in messages, but I’m not completely sure about the context. Any clarity would be appreciated!

BTW stands for “By The Way.” People use it in casual chats to add extra info, change topics, or mention something unrelated.

BTW means “By The Way.”
It is applied to insert some additional data, or change the subject in a casual manner.
E.g. BTW is it your weekend free?
It is widely found on social media, emails and text messages.

BTW is a short term used to denote By The Way. It is applied in written communication that is informal, such as texts, chats, and emails, to bring out a new topic and sometimes slightly related or to make some afterthought or a secondary question.
