Verb tense comparison
Simple Present – Present Progressive

Both these tenses are used to express the present. However, we mostly use the simple present for actions that take place regularly and repeatedly, and the present progressive for actions that are taking place at the moment of speaking.
Օրինակ
He usually wears a hat, but he is not wearing a hat now.
Simple Past – Past Progressive
 
Simple past is the narrative past form. We mostly use it for events that took place one after the other. Past progressive emphasises the progression of an action in the past.
Օրինակ
