In this paper I discuss the passiveness of one pattern in Jewish Babylonian Aramaic, the pattern which consists of the passive participle and the preposition 'l' followed by a pronominal suffix. I will demonstrate that this pattern is indeed a passive construction. For this purpose I will deal with the definition of what a passive construction is in general, then apply this definition to the construction under review, and conclude my discussion by treating some of the possible objections that could be raised against this analysis. As will become clear, this pattern, like similar patterns in other languages, raises the crucial question whether it is possible to have a passive sentence without a clear active partner. This paper will endorse a positive answer to this question.
