I’m hitting that point in my studies where I’m having a really hard time deciding which particle to use in certain sentences. For reference, my grammar is around Genki Level 4 (so I’ve got a long way to go).
Lately, I’ve been mixing up when to use を or が.
Could someone explain why the particles are used the way they are in the following 2 sentences?
I don’t understand Chinese.
Why is が used here instead of を. How would the meaning of the sentence change if I used を or would it just not make sense?
Yesterday, I did not write a letter.
Same question… why is を used instead of が and how would the meaning change if I mixed them up?
Thank you in advance to whoever helps me tackle this problem!
