The correct spelling of the word clonograph is /klɒnəɡræf/. The "o" after "kl" is pronounced as "short o" and the "a" after "gr" is pronounced as "short a". The word is derived from the Greek words "klonos" meaning "twig" or "branch" and "grapho" meaning "to write". A clonograph is a device used to duplicate drawings, maps, or other graphics by tracing them onto a surface using a stylus or pen. It is commonly used in architecture and engineering to create copies of blueprints.
