Questions & Answers about Eu ia estudar, mas desperdiço sempre tempo na plataforma.
How does ia estudar express an "unfulfilled past intention"?
By combining the imperfect tense of ir (which is ia for the eu form, meaning "I was going") with the infinitive estudar. This structure is the standard way to say you planned or intended to do something in the past, but it strongly implies that the action didn't actually happen.
Why does the sentence switch from a past tense (ia) to a present tense (desperdiço)?
In English we say "I always waste", but here it's desperdiço sempre. Does sempre always go after the verb?
Why does the verb desperdiço use a cedilla (ç) here?
The infinitive is desperdiçar. To keep that soft "s" sound when conjugated in the eu form (which ends in -o), you must use the cedilla. If it were spelled desperdico, the "c" before the "o" would make a hard "k" sound.
