Questions & Answers about אני חושבת שסבא יבחר את הספר, וסבתא תבחר את התיק.
Because חושבת is the feminine singular present-tense form of to think.
- אני חושבת = I think / I am thinking said by a woman
- אני חושב = I think / I am thinking said by a man
In Hebrew, present-tense verb forms usually agree with gender and number.
In Hebrew present tense, the verb form usually shows gender and number, but not clearly person.
So חושבת can mean something like:
- I think (if the speaker is female)
- you think (to one female)
- she thinks
That is why אני is important here: it tells you the subject is I.
