אם אני טועה, תגיד לי.

A natural breakdown is:

• אם = if
• אני = I
• טועה = mistaken / wrong / making a mistake
• תגיד = say / tell (masculine singular command)
• לי = to me

So literally, it is something like:

If I am mistaken, tell me.

In natural English, that is often translated as:

• If I'm wrong, tell me.
• Tell me if I'm wrong.

Depending on context, both can work.

Because in the present tense, Hebrew normally does not use a separate verb meaning to be.

So:

• אני טועה = literally I mistaken / I wrong
• but in English we say I am mistaken or I am wrong

This is very normal in Hebrew. Compare:

• אני עייף = I am tired
• היא שמחה = She is happy
• אנחנו בבית = We are at home

In all of these, there is no present-tense am/is/are word.

טועה comes from the verb לטעות, meaning to make a mistake, to be mistaken, or sometimes to be wrong.

So אני טועה can mean:

• I’m mistaken
• I’m wrong
• I’m making a mistake

In this sentence, the most natural sense is:

If I’m wrong / if I’m mistaken, tell me.

It is best understood as the present form of the verb לטעות.

Hebrew present-tense forms often behave a bit like adjectives in agreement, but they are used verbally too. So in:

• אני טועה

טועה is functioning like am mistaken / am wrong.

This is one reason Hebrew present tense can feel different from English: the form looks adjective-like, but it often works as the main predicate of the sentence.

Yes — but in unpointed Hebrew, this particular word is often spelled the same for both.

With pronunciation:

• masculine singular: טועה = to’eh
• feminine singular: טועה = to’ah

So:

• a male speaker would say אם אני טועה
• a female speaker would also usually write אם אני טועה

The difference is mainly in pronunciation, not usually in spelling without vowel marks.

In normal Hebrew, you usually need אני here.

• אם אני טועה = If I’m wrong
• אם טועה sounds incomplete in standard Hebrew

Hebrew often drops subject pronouns in some contexts less than languages like Spanish do. In a sentence like this, אני is the normal and expected form.

Here, אם means if and introduces a condition:

• אם אני טועה = if I’m wrong

Yes, אם can also sometimes mean whether in other contexts. For example:

• אני לא יודע אם הוא יבוא = I don’t know whether he will come

But in your sentence, the meaning is clearly if.

The comma separates the condition from the main command:

• אם אני טועה = conditional part: If I’m wrong
• תגיד לי = main clause: tell me

This is very natural in writing. In speech, you would usually hear a small pause there.

Hebrew punctuation here works much like English:

• If I’m wrong, tell me.

תגיד is a masculine singular imperative-like command form used in everyday Hebrew, from להגיד (to say / to tell).

So it means:

• tell!
• say!

In this sentence:

• תגיד לי = tell me

This is the form you would use when speaking to one male.

The command changes depending on who you are addressing:

• to one male: אם אני טועה, תגיד לי
• to one female: אם אני טועה, תגידי לי
• to more than one person: אם אני טועה, תגידו לי

So only the command changes; אם אני טועה stays the same.

לי means to me.

So:

• תגיד = tell
• לי = to me
• תגיד לי = tell me

Hebrew often uses this pattern with verbs of saying/telling:

• תגיד לי = tell me
• אמרתי לו = I told him
• תספרי לנו = tell us

The indirect object pronoun usually comes after the verb.

Yes, often it can.

English has two common ways to express the same basic idea:

• If I’m wrong, tell me.
• Tell me if I’m wrong.

Hebrew אם אני טועה, תגיד לי most directly matches If I’m wrong, tell me, because the if-clause comes first. But in many situations, the meaning is essentially the same as Tell me if I’m wrong.

A small nuance:

• If I’m wrong, tell me sounds like a condition first
• Tell me if I’m wrong sounds slightly more like a request for correction

But in normal conversation, the difference is often very small.

Both are possible in Hebrew, but they differ in style.

• תגיד לי comes from להגיד
• תאמר לי comes from לומר

Both can mean tell me / say to me, but:

• תגיד לי is very common and conversational
• תאמר לי can sound a bit more formal, literary, or careful depending on context

So אם אני טועה, תגיד לי is a very natural everyday sentence.

A common pronunciation is:

im ani to’eh, tagid li
(if spoken by a male)

If spoken by a female, the טועה would usually be pronounced:

im ani to’ah, tagid li

A rough guide:

• אם = im
• אני = a-NI
• טועה = to-EH / to-AH
• תגיד = ta-GID
• לי = li

The stress is usually on the last syllable in אני, תגיד, and often in the spoken form of טועה as pronounced.

It is natural and idiomatic Hebrew.

A native speaker could definitely say:

אם אני טועה, תגיד לי.

It sounds like a normal conversational way to say:

• If I’m wrong, tell me
• Correct me if I’m wrong

If you wanted a slightly different tone, you could also hear things like:

• אם אני טועה, תתקן אותי = If I’m wrong, correct me
  (to one male)
• אם אני טועה, תגידי לי = same idea, to one female

But your original sentence is perfectly normal.
