> 17. c. transitive. To compose and send a letter to (someone). Now chiefly North American.
In early use with the recipient as an indirect object (in Old English dative object). By the late 18th cent. apparently typically analysed as a direct object, and in Britain viewed as colloquial, or associated with the usage of business and commercial circles. Now viewed as nonstandard in British English and similar varieties, but in standard use in North America.
