Adverb (extremely overused)
In a literal manner or sense.
“Say Literally Again”
In its standard use, literally means ‘in a literal sense, as opposed to a nonliteral or exaggerated sense: “I told him I never wanted to see him again, but I didn’t expect him to take it literally.”
In recent years, an extended use of literally (and also literal) has become very common, where literally (or literal) is used deliberately in nonliteral contexts, for added effect: “They bought the car and literally ran it into the ground.” This use can lead to unintentional humorous effects (“we were literally killing ourselves laughing”) and is not acceptable in formal English. It also tends to drive your friends nuts!
