- Ditransitive verbs have two arguments other than the subject: a patient that undergoes the action and a recipient or beneficiary that receives the patient. In a dechticaetiative language, the recipient of a ditransitive verb is treated in the same way as the single object of a monotransitive verb, and this syntactic category is called primary object. The patient of a ditransitive verb is treated separately and called secondary object.
Etymologically, the first morpheme of the term comes from Ancient Greek dekhomai "to take, receive"; the second is obscure, but it is remotely possible it derives from kaitoi "further, indeed". The term was first introduced by Dr. Edward L. Blansitt, Jr. A more current term for the same phenomenon is secundative language.
