A person who writes down what someone else says or copies written material.
The author hired an amanuensis to help transcribe his handwritten notes into a typed manuscript.
Amanuensis → It is formed from "a-" (meaning from) and "manuensis" (from Latin "manu" meaning hand and "ensis" meaning pertaining to). The word refers to someone who writes down what another person dictates, literally meaning one who writes by hand.
Think of someone who writes 'by hand' ('manu') for another person, which is what an amanuensis does.
