The language has an identifiable Passive construction, defined as follows. There is a special morpheme which can be added to a verb, what is usually the object into the subject, and the subject becomes a non-obligatory oblique phrase. <br><br>For example, in the English sentence <i>The car was driven by John</i>, the <i>-en</i> morphology is added to the verb, <i>the car</i> becomes the subject and <i>John</i> becomes the object of the oblique preposition <i>by</i>. In addition, it can be left out, as in <i>The car was driven</i>. See Siewierska (2008) for more on passives.
