In putting 'morphonology' up for adoption as a chapitre particulier in 1929, Trubetzkoy started a debate regarding the boundary between phonology and morphology that has not ended yet. Essentially a record of a roundtable devoted to that boundary (Montr=E9al, October 1994), Trubetzkoy's Orphan is a full and fascinating picture of some very important contemporary attempts to define it. In addition to papers that focus on it, the volume also contains important papers on the closely related topics of 'morphoprosody' and the 'lexicon', views from 'the floor' and 'the outside', and edited transcripts of the discussions that took place at the Montreal Roundtable. Intended both for practicising and future phonologists and morphologists, Trubetzkoy's Orphan is a valuable record of a very important debate regarding one of the most central questions in phonology and morphology.
