Questions & Answers about אני שומרת כיסא אחד פנוי, כדי שסבתא תשב ליד החלון.
Because שומרת is the feminine singular present-tense form.
The subject is אני = I, and in Hebrew the present tense usually agrees with the speaker’s gender:
- אני שומר = I am keeping / reserving (male speaker)
- אני שומרת = I am keeping / reserving (female speaker)
So this sentence is being said by a woman or girl.
Literally, the verb לשמור often means to guard, to keep, or to watch over. But in everyday Hebrew it can also mean to save, to keep available, or to reserve something.
Here, אני שומרת כיסא אחד פנוי means something like:
- I’m keeping one seat free
- I’m saving one seat
- I’m reserving one seat
So it does not mean the speaker is physically guarding the chair like a security guard. It means she is leaving it available for someone.
