‘Peut-on poser une definition universellement valable des domaines respectifs de la morphologie et de la syntaxe?’ (‘Can one define the fields of morphology and syntax in a way which will be valid universally?’) The question is the last of three proposed for discussion at the Sixth International Congress of Linguists, and the answers given by the participants are printed, with a survey and further interventions, in the proceedings. The congress took place in Paris at a time when travel was more difficult than now, and most people there were European. But according to one of the few participants from North America the answer was quite simply ‘No’. It is time to ask if we can offer any improvement on this answer, and whether, in general, the distinction is as straightforward as we have tended to assume.
