Częste błędy

• Błąd: Using the imperfect indicative instead of the imperfect subjunctive in hypothetical clauses.

  Poprawnie: Use 'Si yo sumara...' not 'Si yo sumaba...'.

  Dlaczego: Hypothetical or contrary-to-fact conditions require the subjunctive mood.

• Błąd: Confusing the -ra and -se forms.

  Poprawnie: Both 'sumara' and 'sumase' are correct for 'yo'. Stick to one ending for consistency if you prefer.

  Dlaczego: While both endings are grammatically correct, learners sometimes get confused about when to use which, or incorrectly think only one is valid.
