Interesting variable name information

Question

I read textbooks all over the Internet with various tutorials indicated in the game (however this turns out to be pretty general).

Are there reasons why many developers name their variables like:

mContext

For me, by default I’ll just call it “context” or something like that.

Are there any reasons why "m" used to be? (I know this is a style issue, but I'm just wondering what that means)
