What Does Cowper. In The Following Webster's Definition Refer To? "5. Hence, A Substitute; A Hostage. --Cowper."
I am using an online dictionary as a reference for the definition of some words and I am uncertain as to meaning and/or reference made by the inclusion of --Cowper. In one of the definitions in Webster's Unabridged Dictionary (1913). Hoping to get some clarity on the matter.
