	abstract = {An attempt is made to establish the systemic significance of the isomorphism between impersonal and modal constructions. While it is natural to express the clear cases of epistemic modality impersonally, there is a choice between personal and impersonal expression when different degrees of {\quotedblbase}objectified{\textquotedblleft} (within the proposition) or root modality are meant. Unlike English, Bulgarian sometimes shows an overt lack of subject-predicate agreement, i. e. the modal verb is impersonal. The analysis of personal constructions denoting epistemic modality shows that the presence or absence of co-reference of the modal and the notional verb to the same subject is a universal means of describing the cline of modal meanings.},

	abstract = {nalysis of the colloquial usage of the Bulgarian neuter pronoun mo shows that the FSP structure of the utterance is of greatest importance. In particular it is the rhematic elements that favour the occurrence of mo in full as well as in one-member sentences. The function of mo has been defined on these grounds. An interpretation of the meaning of mo / it in such sentences has been suggested. It is theoretically possible that in English and other European languages the neuter pronoun behaved once much like mo in Bulgarian. Such an analysis suggests a uniform explanation for the origin of the grammatical subject it in apparently unrelated constructions.},
