Aspect
From UNLwiki
				Aspect is a category used to indicate the temporal internal structure of an event.
Natural language
In the UNLarium, aspect may assume the following values:
{{#tree:id=nl_tense|openlevels=0|root=Aspect (ASP)|
- causative (CAU): causative
 - perfective (PFV): completed
 - imperfective (NPFV): uncompleted
- continuative (CTN): continuous
- progressive (PGS): ongoing
 
 - habitual (HAB): habitual
 - iterative (ITE): repetition
 
 - continuative (CTN): continuous
 - perfect (PFC): relevant to the present
- experiential perfect aspect (EXP): relevant because of the experience
 - perfect of persistent situation (PSS): relevant because of the persistence
 - perfect of recent past (PRP): relevant because of the proximity
 - perfect of result (RES): relevant because of the result
 
 - prospective (PPT): imminent
 - inceptive (ICP): beginning
 - terminative (TER): cessation
 
}}
- Perfect and perfective are different aspectual values
 - perfective = seen as completed (He ate the apple)
 - perfect = seen as relevant to the present (He has eaten the apple)
 
- Aspect values may be combined through "&"
 - I am eating = PGS
 - I have been eating = PGS&PSS
 
Examples
- causative (CAU): He make him ate an apple.
 - perfective (PFV): He ate an apple
 - progressive (PGS): He is eating an apple
 - habitual (HAB): He eats apples.
 - iterative (ITE): He has been eating apples for years
 - experiential perfect aspect (EXP): He has never eaten an apple
 - perfect of persistent situation (PSS): He has been eating that apple since yesterday
 - perfect of recent past (PRP): He has just eaten the apple
 - perfect of result (RES): He has eaten the apple
 - prospective (PPT): He is about to eat the applet
