גם אתה מוזמן לבוא עם בת הזוג שלך, אבל לא היית צריך לקנות מתנה לדוד ולדודה שלי.

גם means also / too.

In גם אתה מוזמן, it emphasizes you too or you are also invited.

Hebrew often places גם right before the word it is adding or emphasizing:

• גם אתה = you too
• גם היא = she too
• גם מחר = tomorrow too

So here, גם comes before אתה because the idea is that you, in addition to someone else, are included.

Hebrew often allows subject pronouns to be omitted, but they can be included for emphasis, contrast, or clarity.

Here, אתה is included because it sounds natural in a sentence like גם אתה מוזמן:

• מוזמן already tells us the subject is masculine singular
• but גם אתה makes the meaning clearer and more emphatic: you too

So the pronoun is not strictly required in every situation, but it is very natural here.

מוזמן here means invited or welcome. It is not the active verb invites.

Compare:

• מזמין = inviting / invites
• מוזמן = invited

So:

• אתה מזמין = you invite
• אתה מוזמן = you are invited / you’re welcome

In this sentence, מוזמן behaves like an adjective or participle describing you, so it agrees with the person being addressed:

• masculine singular: מוזמן
• feminine singular: מוזמנת
• masculine plural: מוזמנים
• feminine plural: מוזמנות

לבוא is the infinitive to come.

After מוזמן, Hebrew often uses an infinitive to say what someone is invited to do:

• אתה מוזמן לבוא = you are invited to come
• את מוזמנת להצטרף = you are invited to join
• אתם מוזמנים לשבת = you are welcome to sit

The ל־ at the start of לבוא is the normal infinitive marker, like to in English.

Literally, בת הזוג שלך means your partner or more literally the daughter/female partner of the pair, yours, but in natural usage it means your female partner, usually:

• girlfriend
• spouse
• romantic partner

Breaking it down:

• בת = daughter / female member of
• זוג = pair / couple
• בת זוג = female partner
• שלך = your

So:

• בן זוג = male partner
• בת זוג = female partner

This phrase is very common in modern Hebrew and is often more neutral than choosing between girlfriend, wife, etc.

In בת הזוג, the ה is the definite article the attached to זוג.

This is a construct-style phrase:

• בת זוג = a female partner
• בת הזוג = the female partner / the partner

Then adding שלך gives:

• בת הזוג שלך = your partner

Hebrew often uses this structure with relationship terms and possessed nouns.

עם means with.

So:

• לבוא עם בת הזוג שלך = to come with your partner

This is just the standard preposition for accompaniment.

Examples:

• אני בא עם חבר = I’m coming with a friend
• היא הלכה עם אחותה = she went with her sister

אבל means but.

It connects the two parts of the sentence and creates a contrast:

• first part: you’re also invited to come with your partner
• second part: but you didn’t need to buy a gift for my uncle and aunt

So it works just like English but.

לא היית צריך is a past form, literally something like you were not needing to, but in natural English it means:

• you didn’t need to
• sometimes, depending on context, you shouldn’t have needed to
• and in some situations it can feel like you didn’t have to

Breaking it down:

• היית = you were (masculine singular)
• צריך = need / supposed to
• לא היית צריך = you didn’t need to / you weren’t supposed to

By contrast:

• אתה לא צריך = you don’t need to / you shouldn’t
  • this is present tense

So the sentence uses לא היית צריך because it is talking about something in the past: buying the gift.

צריך agrees with the person being addressed.

Since the sentence addresses אתה (masculine singular), the form is:

• צריך for masculine singular

Other forms would be:

• את לא היית צריכה = feminine singular
• אתם לא הייתם צריכים = masculine plural
• אתן לא הייתן צריכות = feminine plural

So צריך matches אתה.

After צריך in Hebrew, you normally use an infinitive, just like English need to do.

So:

• צריך לקנות = need to buy
• צריך ללכת = need to go
• צריך לראות = need to see

In the past:

• היית צריך לקנות = you needed to buy
• לא היית צריך לקנות = you didn’t need to buy

Again, the ל־ at the start of לקנות is the infinitive marker, like English to.

מתנה means a gift, not the gift.

So:

• לקנות מתנה = to buy a gift
• לקנות את המתנה = to buy the gift

Because the sentence means an unspecified gift, Hebrew uses the bare noun מתנה with no definite article.

The prefix ל־ here means for / to.

So:

• לדוד = for the uncle / to the uncle
• ולדודה = and for the aunt / and to the aunt

Hebrew often repeats the preposition before each noun in a pair when both are objects of that preposition. That is very natural.

So:

• לדוד ולדודה שלי = for my uncle and aunt

This repeated ל־ is normal and often preferred.

• דוד = uncle
• דודה = aunt

They are related forms:

• masculine: דוד
• feminine: דודה

Hebrew often forms feminine nouns by adding ־ה or a similar ending, so the resemblance is not surprising.

In this sentence, שלי is understood to apply to the whole phrase: my uncle and aunt.

So:

• לדוד ולדודה שלי = for my uncle and aunt

Even though שלי appears only once, Hebrew commonly lets it cover both nouns in a pair. This is very natural.

If you wanted, you could also phrase things differently, but the sentence as written is standard and clear.

Yes. Several forms show that the listener is masculine singular:

• אתה
• מוזמן
• היית
• צריך

If you were speaking to a woman, it would be:

גם את מוזמנת לבוא עם בן הזוג שלך, אבל לא היית צריכה לקנות מתנה לדוד ולדודה שלי.

That changes:

• אתה → את
• מוזמן → מוזמנת
• צריך → צריכה

and possibly בת הזוג → בן הזוג, depending on the meaning you want.
