هي توافق.

• هي is the independent pronoun meaning she (or sometimes it for a feminine noun).
• توافق is a verb in the imperfect tense, from وافق.

So the sentence is basically:

• هي = the subject
• توافق = the action

In fully vocalized MSA, it would usually be written هِيَ تُوافِقُ.

Yes. Arabic often drops subject pronouns because the verb already gives person, number, and gender information.

So توافق can often mean she agrees by itself if the context is clear.

Adding هي can do a few things:

• make the subject extra clear
• add emphasis, like she agrees
• remove ambiguity in writing

This matters because توافق without vowels can also be understood in other ways, especially you agree (masculine singular).

That is a very common question. In the imperfect tense, تـ does not only mark you.

It can mark several different forms, including:

• she
• you (masculine singular)
• you (feminine singular, with a different ending when fully vocalized)

So written without short vowels, توافق is potentially ambiguous on its own.
But once you add هي, the meaning is clearly she agrees.

Yes, it is the imperfect tense, which often corresponds to the English present.

Depending on context, it can mean things like:

• she agrees
• she is agreeing
• she does agree

Arabic imperfect verbs can also refer to the future if the context makes that clear, but if you want an explicit future, Arabic often adds:

• سـ
• سوف

For example:

• هي ستوافق = she will agree

It is grammatical, but it is not the only possibility.

Arabic often allows:

• a verb-first structure
• a pronoun/noun-first structure

With هي توافق, the subject is stated first, which can feel a bit like:

• She agrees
• As for her, she agrees

Using the pronoun first can sound more explicit or contrastive.
In many contexts, Arabic might simply use توافق if the subject is already understood.

In careful MSA pronunciation, it is:

hiya tuwāfiqu

A few details:

• هي = hiya
• توافق = tuwāfiqu

Notes:

• the short vowels are usually not written in normal Arabic script
• the ā in tuwāfiqu is a long vowel
• in pause, the final short vowel -u is often not pronounced clearly, so you may hear something closer to tuwāfiq

Not always. Grammatically, هي is the third-person singular feminine pronoun.

So it can refer to:

• a woman or girl = she
• a feminine singular noun = often it in English

For example, if a previous sentence mentioned a feminine noun such as الخطة (the plan), Arabic could later refer to it with هي.

So depending on context, هي توافق could mean either:

• she agrees
• it agrees / it matches / it is in agreement, if the subject is a feminine noun

Not necessarily. The verb وافق can have several related meanings depending on context, such as:

• agree
• approve
• be in accordance with
• match or correspond to

So even though the meaning has already been given to the learner, it is useful to know that the verb has a wider range than just one English word.

Context decides which English translation fits best.

Because Arabic verbs already carry a lot of grammatical information inside the verb form itself.

In توافق, the verb already tells you things like:

• person
• gender
• number
• tense/aspect

So Arabic does not need a separate helping word for something like:

• does agree
• is agreeing

English often uses extra helper words; Arabic usually builds that information into the verb form itself.
