In the French language the category of aspect is related unevenly either to grammar or style. In French it is not a regular grammatical category. Referring the French verb we cannot indicate whether it expresses a continuous action or a repeated action, as we can do in case of future or past frequentative tense. In the Lithuanian and Slavonic languages the category of aspect is very important, whereas in French it is only the remnant of the defunct grammatical phenomena meeting the occasional needs. After the thorough analysis of the category of aspect in Analytic (French) and Synthetic (Lithuanian, Slavonic languages) languages, the following conclusion could be made: the category of aspect in Lithuanian and Slavonic languages is a binary grammatical category reflecting both abstraction of meanings and oppositional character. This statement is proved by the fact that although the kernel of the category of aspect is made up of the verbs which have different lexical meanings, they can still be juxtaposed as expressing opposed character of one and the same process.
