authored

1. 1
   verb

   Simple past and past participle of author.

   Note

   One spelling does double duty here. It is the simple past (she authored the report) and also the participle, which follows have in perfect tenses and be in passives (the report was authored by a committee). In American usage the verb itself is sometimes objected to. When that objection matters to a reader, wrote or was written by says the same thing without inviting it.

2. 2
   adjective
