Questions & Answers about אני חייבת לצאת עכשיו, כי יש לי פגישה חשובה בעיר.
Because חייבת is the feminine singular form. It tells you the speaker is female.
- אני חייבת = I am obligated / I have to... (female speaker)
- אני חייב = I am obligated / I have to... (male speaker)
This is very common in Hebrew: words like adjectives and participle-like forms often agree with the speaker’s gender.
Not exactly in the same way English must is.
In Modern Hebrew, חייב / חייבת is often used like an adjective or participle meaning obligated or must / have to in context. Hebrew does not usually use a single modal verb exactly like English must here. Instead, it commonly uses:
- חייב / חייבת + infinitive
- צריך / צריכה + infinitive
So אני חייבת לצאת literally feels like I am obligated to leave, but in natural English it is often translated as I have to leave or I must leave.
