that finally makes things clearer to me, pojsc, has to do with isc, right? sorry, i have no accents on this device
It's not. It's a relatively common mistake (especially among older men, I think), but it's wrong. A woman says "poszłam", a man says "poszedłem". Those are the correct forms.
'pójść' is perfective, 'iść' is imperfective. That means that "poszedłem" translates to "I went" and "szedłem" translates to "I was going" - it focuses on the 'process' of going.
