صديقتي تأكل السمك بالسكين والشوكة، وأنا آكل الدجاج بالشوكة فقط.

صديقتي means my (female) friend.

It is made of:

• صديقة = a female friend
• ـي = my

So:

• صديقة → friend (female)
• صديقتي → my female friend

A native English speaker may also notice the ت sound before ـي. That happens because the word ends in ة (taa marbuuTa), and when a suffix like my is added, that ة is pronounced as t:

• صديقة
• صديقتي

If you wanted to say my friend for a male friend, you would say:

• صديقي

Because the verb changes depending on the subject.

• تأكل = she eats
• آكل = I eat

So in the sentence:

• صديقتي تأكل = My friend eats
• وأنا آكل = And I eat

This is a basic feature of Arabic verbs: the subject is built into the verb form.

Arabic often does not use a separate subject pronoun when the verb already shows who is doing the action.

So:

• تأكل already means she eats
• هي تأكل also means she eats, but هي is usually unnecessary unless you want emphasis or contrast

That is why صديقتي تأكل sounds natural:

• صديقتي = my friend
• تأكل = she eats

Arabic does this much more often than English.

Literally, yes:

• السمك = the fish
• الدجاج = the chicken

But in Arabic, the definite article الـ is often used in a more general way than in English, especially with foods, materials, and whole categories.

So:

• تأكل السمك often just means she eats fish
• آكل الدجاج often just means I eat chicken

This does not always mean one specific fish or one specific chicken. It can simply refer to the food in general.

Here بـ means with / using, showing the instrument used to do something.

So:

• بالسكين = with a knife / using a knife
• بالشوكة = with a fork / using a fork

This بـ is attached directly to the noun.

Because the noun has الـ, the combination becomes:

• ب + السكين → بالسكين
• ب + الشوكة → بالشوكة

So the sentence is talking about what utensils are used for eating.

Both are possible, but بالسكين والشوكة is very natural.

Arabic often uses the preposition once before the first noun, and then joins the second noun with و:

• بالسكين والشوكة = with a knife and fork

This is similar to English, where we usually do not repeat with:

• with a knife and fork not usually
• with a knife and with a fork

If you said بالسكين وبالشوكة, it would still be understandable, but it sounds more repetitive or more emphatic.

Yes, Arabic could sometimes say وآكل الدجاج..., but وأنا is very natural here because it creates a clear contrast:

• صديقتي تأكل السمك...
• وأنا آكل الدجاج...

This feels like:

• My friend eats fish..., and I eat chicken...

Using أنا makes the contrast clearer:

• she ... , but/as for me, I ...

So وأنا is a natural choice when comparing two people.

Because the pronoun can be added for emphasis, clarity, or contrast.

• آكل by itself already means I eat
• أنا آكل means I eat, but with extra emphasis on I

In this sentence, أنا helps set up the contrast with صديقتي:

• My friend eats fish with a knife and fork,
• and I eat chicken with only a fork.

So the pronoun is not required for grammar, but it is useful for style and meaning.

فقط means only.

In:

• بالشوكة فقط

it means:

• with only a fork or
• using a fork only

Placing فقط after the phrase it modifies is very common in Arabic.

So:

• بالشوكة فقط = only with a fork
• فقط بالشوكة can also occur in some contexts, but بالشوكة فقط is the most straightforward here

Arabic word order is more flexible than English.

This sentence uses a very common pattern:

• subject + verb + object + phrase
• صديقتي تأكل السمك بالسكين والشوكة

English also uses this pattern:

• My friend eats fish with a knife and fork

But Arabic can often rearrange parts more freely, especially for emphasis. For example, the verb can sometimes come before the subject in other sentences:

• تأكل صديقتي السمك

That also means:

• My friend eats fish

So learners should know that Arabic word order is flexible, even if this sentence looks fairly close to English.

شوكة is grammatically feminine because it ends in ة.

In this sentence, that does not change much, because it comes after the preposition بـ:

• بالشوكة

But in other contexts, grammatical gender matters because adjectives, pronouns, and verbs may agree with the noun.

For example:

• الشوكة كبيرة = The fork is big
• السكين كبير = The knife is big

So yes, it matters in Arabic grammar, even though here it is just part of a prepositional phrase.

In fully vocalized formal Arabic, case endings can appear, for example:

• صديقتي تأكلُ السمكَ بالسكينِ والشوكةِ، وأنا آكلُ الدجاجَ بالشوكةِ فقط.

But in normal Arabic writing, short vowels and case endings are usually not written.

So learners usually see:

• صديقتي تأكل السمك بالسكين والشوكة، وأنا آكل الدجاج بالشوكة فقط.

This is completely normal.

In other words:

• the grammar is still there
• the short ending vowels are just usually omitted in writing

In this sentence, بـ is the better choice.

• بـ is commonly used for the instrument or tool used to do something:
  • بالسكين = using a knife
  • بالشوكة = using a fork

مع usually means with in the sense of together with or accompanied by, not usually the instrument itself.

So:

• آكل بالشوكة = I eat with a fork ✔
• آكل مع صديقتي = I eat with my friend ✔

That is an important difference:

• بـ = by means of / using
• مع = together with

Yes, they can, depending on context.

• السمك can mean fish as animals or as food
• الدجاج can mean chickens or chicken as food

In this sentence, because the verbs and utensils are about eating, the meaning is clearly food:

• تأكل السمك = eats fish
• آكل الدجاج = eat chicken

So context tells you which meaning is intended.
