In Polish the negative perfective imperative is actually a specific syntactic mood, the cautioning mood (Nie wylej tei wody!). Such a form of the imperative is impossible in modern standard Bulgarian (cf. Да не излееш водата!). The explanation of the expressiveness of this construction is to be sought in the aspectual semantic features of the verbal forms in the light of some of the latest studies of the category of aspect.1 aМилева, Виолета  uhttp://www.scripta-bulgarica.eu/en/node/3939
