Questions & Answers about קיבלתי הזמנה לחתונה, וגם אחותי מוזמנת.
Because קיבלתי already includes I.
In Hebrew, the verb often tells you who the subject is, especially in the past tense. The ending ־תי means I. So:
- קיבלתי = I received
You can add אני if you want emphasis or contrast, but it is not necessary here.
קיבלתי comes from the verb לקבל, meaning to receive.
A useful way to see it is:
- קיבל = he received
- קיבלתי = I received
The ending ־תי is the regular past-tense ending for I in many Hebrew verbs.
