Learn Hardcore Hebrew: אני שומעת אותם מדברים בחדר, אבל אני לא רואה אותם מהמטבח. - I hear them talking in the room, but I do not see them from the kitchen.

אני means I for both men and women.
The verb shows the gender:
- אני שומע = I hear (male speaker)
- אני שומעת = I hear (female speaker)

If the speaker is female, why is רואה not ending in -ת like שומעת?

Not all Hebrew verbs form the feminine singular present tense the same way.

The verb לראות (to see) is one of the verbs whose masculine and feminine singular present forms are both written רואה in normal unpointed Hebrew spelling.

masculine: רוֹאֶה
feminine: רוֹאָה

So the spelling looks the same, but the form is still feminine here because the sentence already shows a female speaker with שומעת, and the subject is the same אני.

What does אותם mean here?
