Questions & Answers about אין לי ספק לגבי התוצאה.
אין is the word used to express non-existence / absence in the present tense, often equivalent to there is no / I don’t have.
So:
אין לי ספק = I have no doubt
Literally: There is no doubt to me
By contrast, לא is the regular word for not, used to negate verbs and other statements, for example:
אני לא יודע = I don’t know
So in this sentence, אין is correct because Hebrew is expressing that no doubt exists for the speaker.
Because Hebrew often expresses having with a structure like there is / there isn’t + to someone.
So:
- יש לי = I have
- אין לי = I don’t have
Here, לי literally means to me.
So:
אין לי ספק
Literally: There is no doubt to me
Natural English: I have no doubt
This is a very common Hebrew pattern, and it is one of the first big differences from English.
