Questions & Answers about הייתי מאוכזבת מהארוחה במסעדה, ולכן לא רציתי לחזור לשם.
הייתי is the past-tense form of להיות (to be) for I.
So הייתי מאוכזבת means I was disappointed.
A useful point for English speakers: in Hebrew, the subject pronoun אני is often left out because the verb already shows the person. So:
- הייתי מאוכזבת = I was disappointed
- אני הייתי מאוכזבת = also possible, but more emphatic
Because Hebrew adjectives agree with the gender of the person they describe.
Here, מאוכזבת is the feminine singular form of disappointed. That means the speaker is female.
- מאוכזבת = disappointed, feminine
- מאוכזב = disappointed, masculine
Notice that הייתי itself does not show gender in the I form. The gender is clear only because of מאוכזבת.
