Questions & Answers about יש מספיק סוכר לקפה, אבל אין מספיק מלח למרק.
Because Hebrew commonly uses יש and אין to talk about existence or availability.
- יש מספיק סוכר = there is enough sugar
- אין מספיק מלח = there isn’t enough salt
So here, the sentence is not using a normal present-tense verb like English is / isn’t. Instead, Hebrew uses:
- יש = there is / there are
- אין = there isn’t / there aren’t
This is extremely common in Hebrew.
Because אין is the special negative partner of יש.
In standard Hebrew:
- יש = there is / there are
- אין = there is not / there are not
You normally do not say לא יש.
Compare:
- יש זמן = there is time
- אין זמן = there is no time
By contrast, לא is used to negate regular verbs and many other sentence types:
- אני לא יודע = I don’t know
- הוא לא בא = he isn’t coming
So in this sentence, אין is exactly the right form.
