Fernando zúñiga. Selected semitransitive constructions in Algonquian. the poznań Society for the advancement of arts and Sciences, pL ISSn 0079-4740, pp. 211-229 the present paper surveys a number of selected constructions in algonquian languages that fall between those expressing transitivity and those expressing intransitivity (hopper & thompson 1980;Dryer 2007). Socalled passives are mostly agentless and show different kinds of allomorphy in the particular languages. antipassives are not fully understood yet but seem to be more idiosyncratic than passives, and are not found everywhere in the family. Lastly, systematic mismatches between morphological and syntactic valency (similar to constructions found in oceanic and other languages) seem to play an important role in the inventory of constructions used to express less than full transitivity in algonquian.
