Liaise

Liaise

Verb · /liˈeɪz/

Definition

To establish and maintain communication or cooperation between people or groups for their mutual benefit; to act as a link between parties.

Origin

A back-formation from liaison (from French liaison — a linking, from lier — to bind, from Latin ligare). Liaise was formed by English speakers who treated liaison as if it derived from an original verb liaise. Liaise appeared in British military usage in World War I, spreading into general use from the 1920s. It is considered informal to standard depending on context.
