Aspect in Scottish Gaelic
Aspect takes two forms in Scottish Gaelic: (1) Grammatical or Viewpoint aspect and (2) Lexical aspect or Aktionsart. Viewpoint aspect gives a picture of the flow or architecture of the time of the situation expressed by the proposition. Aktionsart is inherent to verbs or verb phrases and describes the inherent structure of the eventuality of the proposition in terms of endpoints (telicity) and duration (punctualness/durativity), etc.
