علاقتنا كويسة.

علاقتنا = علاقة + نا

• علاقة = relationship
• ـنا = our

So علاقتنا literally means our relationship.

A useful thing to notice: the ـة at the end of علاقة changes in pronunciation when a suffix is added. So on its own you might hear ʿalāʔa, but علاقتنا is pronounced more like ʿalāʔetna / ʿalaʔetna in Egyptian speech.

Because علاقة is a feminine noun, and the adjective has to agree with it.

• masculine: كويس = good
• feminine: كويسة = good

Since علاقتنا refers to علاقة, which is feminine, you say:

• علاقتنا كويسة

not

• علاقتنا كويس

In Arabic, the verb to be is usually not stated in the present tense.

So:

• علاقتنا كويسة literally looks like our relationship good
• but it naturally means our relationship is good

This is very normal in both Egyptian Arabic and Standard Arabic.

If you wanted past tense, then you would use a verb, for example:

• علاقتنا كانت كويسة = our relationship was good

A common pronunciation is:

• ʿalaʔetna kwayyisa

You may also see it written in Latin letters as:

• 3ala2etna kwayyisa
• ala2etna kowaysa / kwayyisa

A few pronunciation notes:

• ع is the sound ʿayn, which English doesn’t really have.
• The ق in Egyptian Arabic is often pronounced like a glottal stop ء, so علاقة sounds like ʿalāʔa rather than ʿalāqa.
• كويسة is often pronounced kwayyisa.

This sentence is clearly colloquial, and it fits Egyptian Arabic very well.

The main colloquial clue is كويسة. In Standard Arabic, you would be more likely to say something like:

• علاقتنا جيدة
• علاقتنا طيبة

In Egyptian Arabic, كويس / كويسة is one of the most common ways to say good.

So if you say علاقتنا كويسة, it sounds natural in Egyptian speech.

It can absolutely mean we’re on good terms depending on context.

Possible natural English translations include:

• Our relationship is good
• We’re on good terms
• Things are good between us

The exact best translation depends on the situation. If two people are talking about how they get along, the meaning is often closer to we’re fine with each other or we have a good relationship.

Because when you attach a possessive suffix like ـنا (our), the word changes form slightly.

With nouns ending in ـة:

• the ـة is pronounced more like t when something is attached after it

So:

• علاقة = relationship
• علاقتنا = our relationship

This is a very common pattern in Arabic. Compare:

• عربية = a car / Arabic (depending on context)
• عربيتي = my car

The t sound appears when the suffix is added.

Yes, كويسة can be used for both:

1. a feminine noun
2. a female person

Examples:

• العلاقة كويسة = the relationship is good
• هي كويسة = she is good / she’s nice / she’s okay

So in your sentence, it is feminine because it describes علاقة, not because it tells you anything about the speaker.

Yes, grammatically you can, but it sounds more formal or bookish than علاقتنا كويسة.

Compare:

• علاقتنا كويسة = natural everyday Egyptian Arabic
• علاقتنا جيدة = more Standard Arabic / formal style

If you are learning spoken Egyptian, كويسة is the more useful everyday choice.

علاقتنا كويسة is the normal and most natural order.

It follows a very common Arabic pattern:

• noun + adjective

So:

• علاقتنا = our relationship
• كويسة = good

You may sometimes hear different word orders for emphasis in speech, but for a learner, علاقتنا كويسة is the best default.

It can be used in many situations. علاقة is a general word for relationship.

So it could refer to:

• a romantic relationship
• a friendship
• a family relationship
• a work relationship
• the general connection between two people

The context tells you what kind of relationship is meant.

For example, if two coworkers are talking, علاقتنا كويسة would probably mean we get along well. If a couple is talking, it could mean our relationship is good in the romantic sense.

A few natural alternatives are:

• إحنا كويسين مع بعض = we’re good together / we’re on good terms
• الدنيا بينا كويسة = things between us are good
• مفيش مشاكل بينا = there are no problems between us

These are not exact word-for-word replacements, but they are common ways to express a similar idea in Egyptian Arabic.
