היא ביקשה ממני לא לספר לאף אחד את הסוד שלה.

Because the subject is היא (she).

• ביקשה is the 3rd person feminine singular past form of לבקש (to ask / to request).
• If the subject were he, it would be הוא ביקש.
• So היא ביקשה = she asked / she requested.

Because with לבקש in the sense of asking someone to do something, Hebrew usually uses מ־ (from) before the person:

• לבקש ממישהו לעשות משהו = to ask someone to do something

So:

• היא ביקשה ממני = literally she asked from me
• but in natural English: she asked me

This is a very common difference between Hebrew and English.

Also, be careful:

• לבקש מישהו can mean to ask for someone / look for someone
• לבקש ממישהו means to ask someone

ממני means from me.

It is built from:

• מ־ / מן = from
• אני = I

But Hebrew does not keep them separate here. Instead, they combine into the fixed form:

• ממני = from me

Other similar forms:

• ממך = from you (m. sg.)
• ממך = from you (f. sg.)
• ממנו = from him
• ממנה = from her

So ביקשה ממני is literally asked from me.

Because לא לספר means not to tell.

After verbs like ביקש (asked), Hebrew often uses:

• לא + infinitive

So:

• לספר = to tell
• לא לספר = not to tell

In this sentence:

• היא ביקשה ממני לא לספר...
• She asked me not to tell...

לספר is the infinitive of the verb סיפר (to tell).

So:

• סיפר = he told
• לספר = to tell

This is the normal dictionary-style infinitive form in Hebrew, often beginning with ל־.

In the sentence, it depends on ביקשה:

• ביקשה... לא לספר = asked... not to tell

Yes, it is a kind of double negative, and that is normal in Hebrew.

Hebrew often uses negative concord, where more than one negative-looking word appears in the same sentence:

• לא... אף אחד
• literally: not... no one
• natural English: not... anyone

So:

• לא לספר לאף אחד
  literally = not to tell to no one
• natural English = not to tell anyone

This is completely standard Hebrew.

לאף אחד means to anyone / to no one, depending on the sentence.

It is made of:

• ל־ = to
• אף אחד = anyone / no one

Because the whole sentence is negative (לא לספר), לאף אחד is understood as to anyone in English:

• לא לספר לאף אחד = not to tell anyone

Without context, אף אחד often appears in negative sentences.

את is the Hebrew direct object marker.

It appears before a definite direct object, usually one with:

• ה־ (the)
• a possessive ending
• a proper name
• or another definite expression

Here, הסוד שלה (her secret) is definite, so Hebrew uses את:

• את הסוד שלה

Important: את is usually not translated into English.
It just marks that the secret is the direct object of לספר.

Compare:

• לספר סוד = to tell a secret
• לספר את הסוד = to tell the secret

Both are possible.

• הסוד שלה = her secret
• סודה = her secret

The version in your sentence, הסוד שלה, is very common and natural, especially in everyday speech. It can sound a little clearer and more explicit.

A more compact version would be:

• היא ביקשה ממני לא לספר לאף אחד את סודה

That is also correct.

Very roughly:

• הסוד שלה feels a bit more conversational and transparent for learners
• סודה is shorter and a bit more literary or formal in some contexts

Usually yes, in this sentence the natural reading is:

• היא = she
• הסוד שלה = her secret, meaning the same woman’s secret

But grammatically, שלה just means hers / her.
In a different context, it could refer to another female person already mentioned.

So Hebrew, like English, sometimes relies on context to make it clear whose secret it is.

The sentence as written is very natural:

• היא ביקשה ממני לא לספר לאף אחד את הסוד שלה

But Hebrew word order is somewhat flexible. You could also hear:

• היא ביקשה ממני לא לספר את הסוד שלה לאף אחד

This also means the same thing: She asked me not to tell anyone her secret.

The original version puts לאף אחד earlier, which feels very natural because it highlights not to anyone before mentioning the secret.

No, not here.

Because of the structure:

• ביקשה ממני לא לספר...

it clearly means:

• she asked me not to tell...

If Hebrew wanted to say she asked for me or she was looking for me, it would usually be something like:

• היא ביקשה אותי in certain contexts is not the normal way to say she asked me
• more often, Hebrew uses different phrasing depending on the intended meaning

So in this sentence, ממני makes the meaning clear: she asked me.

Yes.

The verb לבקש can mean:

• to ask
• to request
• sometimes to seek / to ask for, depending on context

In this sentence, asked is the most natural English translation:

• She asked me not to tell anyone her secret

But requested is also grammatically possible, just slightly more formal in English.
