Amanuensis

An amanuensis (/əˌmænjuˈɛnsɪs/) is a person employed to write or type what another dictates or to copy what has been written by another. An amanuensis may also be a person who signs a document on behalf of another under the latter's authority.

In some academic contexts, an amanuensis can assist an injured or disabled person in taking written examinations. Eric Fenby acted as an amanuensis in assisting the blind and paralysed composer Frederick Delius in writing down the notes that Delius dictated.
