The title of the page is: forming el Imperfecto Progresivo con estar + gerundio but the next paragraph jumps to the Pretérito Imperfecto:
“In the case of El Pretérito Imperfecto, this is how the progressive tense is formed.”
Is the pretérito imperfecto and the imperfecto progresivo the same tense, just a different name?
Thank you.
