The article considers the interaction of tense and aspect with verbs expressing hypothetic modality in Modern Greek, Modern Bulgarian and Modern Polish (as a representative of Northern Slavic) with a special attention to the paradoxical ability of the Greek and the Bulgarian modal imperfect to denote momentary actions or their result. It claims that in the past tenses the meaning of the Greek verbal stem is more temporal and modal and less aspectual, while in the future tense, in the imperative and in subjunctive constructions it shows a considerable semantic symmetry with Bulgarian and Northern Slavic verbal aspect.
