IPA: /ˈdjuːplɪˌkeɪtə/
KK: /ˈduːplɪˌkeɪtə/
A device that makes copies of documents or images, often used in offices to reproduce printed materials.
The office bought a new duplicator to handle all their printing needs.
Duplicator → It is formed from "duplex" (from Latin, meaning twofold or double) and "-ator" (a suffix used to indicate an agent or doer). The word "duplicator" refers to a device or person that makes duplicates or copies, essentially creating something double.
Think of something that makes 'two' ('duplex') of something — that's why a duplicator is a device that creates copies.
