The term 'aspect'; designates the perspective taken on the internal temporal organisation of the event, and different values of the Aspect Feature distinguish different ways of viewing the internal temporal constituency of the same event [Comrie 1976, 3ff], after [Holt 1943, 6; Bybee 2003, 157]. The 'event is understood here as a general term covering any situation type (a state, activity, accomplishment, achievement, etc.) as expressed by the verb phrase of the construction. Unlike Tense Feature, which expresses event-external time and is deictic, Aspect Feature is event-internal and non-deictic, as it is not concerned with relating the time of the event to any other time point. Aspect Property is assigned to clauses on the basis of semantics: an aspect value is selected for the clause from the range of aspect values available in the given language. Aspect Property is typically realised on the verb, but it may be found expressed multiply on different elements in the same clause. It may be found on more than one element of the verbal complex, or on verbs as well as certain adverbs in the same clause. In the given language, the values of the Aspect Property are assigned to the designated elements as a consequence of semantic choice, and all the available options of particular aspect values expressing particular aspect meanings can be described with an Aspect Assignment System for that language. Since no languages have been found for which aspect values are assigned by an Aspect Distribution System (i.e. contextually, through agreement or government), Aspect Feature is not a Morphosyntactic Property. Instead, it is a Morphosemantic Property only. NOTE: Although the semantic basis for the Aspect Property are the distinctions identified in the internal temporal constituency of an event, aspect meanings frequently combine with tense, modal or other meanings expressing actionality distinctions. Hence, markers expressing aspect values are frequently portmanteaux realising combined TAM values.
