In Ancient Greek, the perfect tense (Ancient Greek: χρόνος παρακείμενος, romanized: khrónos parakeímenos) [9] is a set of forms that express both present tense and perfect aspect (finite forms), or simply perfect aspect (non-finite forms). However, not all languages conflate tense, aspect and mood.
