Etymology
Origin of rap1
First recorded in 1300–50; 1960–65 rap 1 for def. 8; Middle English verb rappen; akin to Swedish rappa “to beat, drub,” German rappeln “to rattle”; the senses “to talk” and “conversation, talk” are perhaps of distinct origin, though the hypothesis that these meanings are a shortening of repartee is questionable
Origin of rap2
First recorded in 1715–25; origin uncertain
Origin of rap3
First recorded in 1520–30; back formation from rapt
Explanation
To rap is to hit something, talk, or bust into rhymes like the Fat Boys in the rap song “Human Beat Box” (1984). That’s some old school Brooklyn rap, but you can rap to any beat you want. Hit it! A rap is a knock or blow, like if you rap somebody upside the head as a gentle reminder to pay attention. The word rap also means, "reputation,” like if you get a bad rap at school for sleeping in class. It’s also "to talk at great length." And there’s the musical rap, the “genre that includes talking rhythmically over a beat.” This meaning comes from African American slang for, basically, "talking.”
