The term 'copy, in a way' can be defined by four different five-letter words: MIMEO, XEROX, CLONE, and TRACE. MIMEO is short for mimeograph, which is a duplicating machine that uses a stencil to make copies of documents. XEROX is a brand name for a photocopier, which uses light to create copies of documents. CLONE refers to the process of making an exact copy of something, such as a gene or a computer program. Finally, TRACE is a verb meaning to make a copy of something by tracing it with a pencil or pen.
