Latin is a highly flective language, which is a condition for developing the morphological aspect; there are also no articles, which are important carriers of the aspect in Germanic languages. It follows that we might expect the morphological aspect in Latin, however, it obviously is not systematic in its whole verbal system - it has never developed in such a complex form.
Since Romance languages have a developed aspectual system, classical Latin seems to be halfway to gramaticalization of the aspect. In the present paper the possible aspectual markers in Latin are isolated and their mutual relationships discussed.
