Conditionals theory in Hebrew grammar is an important aspect that allows speakers to express hypothetical or conditional situations. There are various types of conditional sentences in Hebrew, each of which follows certain syntactical and grammatical rules.

One type of conditional sentence in Hebrew is the simple conditional, which is expressed through the use of the word “אם” (if) followed by the simple future tense. For example, “אם אני יכול, אני אבוא” (If I can, I will come).

Another type of conditional sentence is the present unreal conditional, which is used to express things that are unlikely or impossible to happen in the present. It is formed by combining the word “אם” (if) with the present tense of the verb followed by the prefix “לא”. For example, “אם היתה לי כסף, הייתי קונה אותו” (If I had money, I would buy it).

Additionally, Hebrew also has a past unreal conditional, which uses the past tense of the verb in combination with the word “אם” (if) followed by the prefix “לא”. For example, “אם הייתי יודע, הייתי אמרתי” (If I had known, I would have said).
