(Clements 1975: 158-9 (Pan 2001: 291) While the logophoric pronoun yè in Ewe, one of the West African languages, in (2a) can be co-referential with either the matrix subject Ama or oblique Kofi, which functions as the source of the given reportive context, that in (2b) can only refer to Kofi with the thematic function of source, but not the first person pronoun me 'I'.
the sentence in (2b) is unacceptable when the first person pronoun me 'I' is an antecedent of the logophoric pronoun yè because the referent of a logophoric pronoun should be in the third person.
