perfective aspect vs stunning

perfective aspect

noun
  • A feature of the verb which denotes viewing the event the verb describes as a completed whole, rather than from within the event as it unfolds. For example, "she sat down" as opposed to "she was sitting down". Since the focus is on the completion of what is expressed by the verb, this aspect is generally associated with the past and future tenses. This term is often used interchangeably with aorist aspect. This is not to be confused with the perfect tense. 

stunning

noun
  • The act by which a person or animal is physically stunned. 

adj
  • Exceptionally beautiful or attractive. 

  • Having an effect that stuns. 

  • Amazing; wonderfully good.
