In linguistics, boundedness is a semantic feature that relates to an understanding of the referential limits of a lexical item.
[2] Though this feature most often distinguishes countability in nouns and aspect in verbs, it applies more generally to any syntactic category.
Boundedness is characteristic of perfective aspects such as the Ancient Greek aorist and the Spanish preterite.
In German, the modal particle "mal" can be used to express that the speaker renounces the exactness and temporal unambiguity of the action of the verb, favoring vagueness and non-commitment.
[3] In order for a noun to be semantically bounded, its referent item, whether tangible or abstract, must have clearly defined limits on the extent and content of what it encompasses.
