TO DO: - Make the \REF{} particle a topic marker, otherwise top-level sentences are not disambiguatable (`The son has a father', `The father has a son.'). (DONE, I think. Check this.) - Make re-positioning words be full verbs, too, like some in Mandaring: shang4, xia4 can function as postpositions: zai4 yi3zi shang4 you3 shu1. (CHECK tone of yizi) or verbs: wo3 shang4 che1. - decide how to cope with gapping: X is rich and drives a car. Problem here: Patient: rich X. Agent: X move car. So we may need something to compose this. E.g. something like passive/antipassive or the like. But I do not want to have another grammar rule. Maybe even disallow it and require a back reference via pronoun: A is rich and <s/he> drives a car. This is likely to introduce structures that violate the increasing control constraint, however. - have no resultative and inchoative verbs in the lexicon. - repair the sample sentences according to this. - repair the lexicon according to this.
