هي تستشير أمين المكتبة.

A word-by-word breakdown is:

• هي = she
• تستشير = consults / is consulting / consults with
• أمين = keeper, custodian, person in charge
• المكتبة = the library

Together, أمين المكتبة literally means the keeper/custodian of the library, which is the usual Arabic way to say the librarian.

So the whole sentence means She consults the librarian.

هي is the independent pronoun meaning she.

Arabic verbs already show the subject, so تستشير by itself already tells you the subject is she or sometimes you (feminine singular), depending on context. Adding هي makes the subject explicit.

So:

• تستشير أمين المكتبة = She consults the librarian / You (feminine) consult the librarian, depending on context
• هي تستشير أمين المكتبة = clearly She consults the librarian

In many cases, Arabic can omit the pronoun if the verb already makes the subject clear.

In the present tense, Arabic often uses prefixes to show who is doing the action.

Here, تـ marks:

• she
• or you (feminine singular)

So تستشير can mean:

• she consults
• you consult (said to one female)

Because the sentence includes هي, we know it means she consults.

Yes. تستشير is a present/imperfect verb form.

In English, this Arabic form can match several translations depending on context, such as:

• she consults
• she is consulting
• she consults regularly
• sometimes even she will consult, if the context points to the future

Arabic present-tense verbs are often broader in meaning than a single English tense.

It is the present-tense form of استشار = to consult / seek advice from.

Its dictionary form is usually given as:

• استشار = he consulted
• يستشير = he consults / is consulting

So:

• هي تستشير = she consults

This verb is commonly followed by a direct object: the person being consulted.

In Arabic, استشار usually takes a direct object, so no preposition is needed here.

That means Arabic says, literally:

• She consults the librarian

not:

• She consults with the librarian

So أمين المكتبة is the direct object of تستشير.

This is because أمين المكتبة is an iḍāfa construction, often called a genitive construction or noun + noun possession structure.

Structure:

• أمين = keeper/custodian
• المكتبة = the library

Together:

• أمين المكتبة = the library’s keeper = the librarian

In an iḍāfa:

1. The first noun usually does not take الـ
2. The second noun can make the whole phrase definite if it is definite

So because المكتبة has الـ, the whole phrase أمين المكتبة is definite and means the librarian, not just a librarian.

Yes. In an iḍāfa construction, the second noun is in the genitive case.

So in fully vocalized Arabic, the phrase would be:

• أَمِينَ الْمَكْتَبَةِ

Here:

• أمِينَ is accusative because it is the direct object of the verb
• المكتبةِ is genitive because it is the second part of the iḍāfa

In normal everyday writing, these short vowel endings are usually not written, so you just see:

• أمين المكتبة

It would typically be:

• هِيَ تَسْتَشِيرُ أَمِينَ الْمَكْتَبَةِ

With case endings:

• هِيَ = she
• تَسْتَشِيرُ = the verb, usually ending in ـُ
• أَمِينَ = direct object, so accusative ـَ / ـينَ
• الْمَكْتَبَةِ = genitive after iḍāfa, so ـِ

In normal Arabic texts, these endings are usually omitted.

Yes. Arabic often leaves out subject pronouns because the verb already shows the subject.

So you can say:

• تستشير أمين المكتبة

and it can still mean She consults the librarian, as long as the context makes it clear.

Adding هي is useful when you want to:

• make the subject explicit
• emphasize she
• avoid confusion with you (feminine singular)

Yes. This sentence uses subject + verb + object:

• هي = subject
• تستشير = verb
• أمين المكتبة = object

Arabic also often uses verb + subject + object, but when the subject is an independent pronoun like هي, placing it first is very natural.

So this sentence is perfectly normal.

Yes. أمين is grammatically masculine.

If the librarian is female, you would typically say:

• أمينة المكتبة = the female librarian

Then the sentence would be:

• هي تستشير أمينة المكتبة = She consults the female librarian

A rough pronunciation guide is:

• ta-sta-sheer

More carefully:

• تس = tas
• تشير here sounds like ta-sheer overall within the word
• the ش sound is like English sh
• the ي here gives a long ee sound

So تستشير sounds approximately like tastashīru in fully vocalized pronunciation.

Literally, it means custodian/keeper of the library.

In actual usage, it is the normal formal Arabic expression for librarian. So you should understand it as a job title, even though the literal meaning is more descriptive.

This kind of wording is very common in Arabic.
