clone n. 1. An exact duplicate "Our product is a clone of their product." Implies a legal reimplementation from documentation or by reverse-engineering. Also connotes lower price. 2. A shoddy, spurious copy: "Their product is a clone of our product." 3. A blatant ripoff, most likely violating copyright, patent, or trade secret protections: "Your product is a clone of my product." This use implies legal action is pending. 4. `PC clone:' a PC-BUS/ISA or EISA-compatible 80x86-based microcomputer (this use is sometimes spelled `klone' or `PClone').

To make an exact copy of something. "Let me clone that" might mean "I want to borrow that paper so I can make a photocopy" or "Let me get a copy of that file before you mung it".
