"Del" can refer to different things depending on the context. Here are a few possibilities: 1. **Key on Keyboard**: The "Del" key, short for "Delete," is a key on computer keyboards. It is used to delete text or objects in various software applications. 2. **Mathematics**: In mathematics, particularly in vector calculus, "Del" (often represented as the symbol ∇) refers to the vector differential operator.
Oh, and if it weren't enough, mathematicians have a separate name for the damned nabla symbol : "del" instead of "nabla".
