A 'dechticaetiative language' is a language in which the
indirect objects of
ditransitive verbs are treated like the
direct objects of
monotransitive verbs. Etymologically, the first morpheme of the term comes from Gk ''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.
Ditransitive verbs have two arguments other than the subject: a 'patient' that undegoes the action and a 'recipient' or 'beneficiary' that receives the patient (see
thematic role). 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'.
In dechticaetiative languages with
passive constructions, passivisation promotes the primary object to subject.
Most dechticaetiative languages are found in
Africa, but
English arguably contains dechticaetiative constructions, traditionally referred to as
dative shift. For example, the passive of the sentence ''John gave Mary the ball'' is ''Mary was given the ball by John'', in which the recipient rather than the patient is promoted to subject. This is complicated by the fact that some dialects of English may promote either the recipient (''Mary'') or the patient (''the ball'') argument to subject status, and for these dialects ''The ball was given Mary by John'' (meaning that the ball was given to Mary) is also well-formed.
