قبض گاز هنوز نیامده است، اما باید اجاره خانه را زود پرداخت کنیم.

There actually is a link there: the ezafe sound.

So these are pronounced roughly as:

• قبضِ گاز = ghabz-e gāz
• اجارهٔ خانه / اجاره‌ی خانه = ejāre-ye xāne

In normal Persian writing, short vowels are usually not written, so you do not see the -e sound after قبض. The same thing happens in اجاره خانه, where the phrase is understood as rent of the house / house rent.

قبض can mean bill, utility bill, or sometimes receipt, depending on context.

In this sentence, because it is followed by گاز, it means gas bill. You will also see similar phrases like:

• قبض برق = electricity bill
• قبض آب = water bill

نیامده است is the negative present perfect of آمدن = to come.

• آمده است = has come
• نیامده است = has not come

In Persian, for things like letters, bills, packages, and messages, آمدن is often used where English would say arrive. So قبض گاز هنوز نیامده است literally means the gas bill still has not come, which is naturally translated as the gas bill still hasn't arrived.

This is the normal negative form of آمده in modern Persian: نیامده.

Because آمده begins with a vowel sound, Persian uses نی- here rather than a form that would be awkward to pronounce. So you should simply learn نیامده as the standard negative perfect-participle form of آمدن.

هنوز means still or yet, depending on how you translate it into natural English.

In a negative sentence like this, هنوز نیامده است can be understood as either:

• still hasn’t arrived
• hasn’t arrived yet

So هنوز shows that the speaker expected the gas bill by now, but it has not come up to the present moment.

را marks the direct object, especially a specific one.

Here, اجاره خانه را means that the rent is the thing being paid. The را does not have a direct English translation, but it helps show what the verb acts on.

So in this sentence:

• اجاره خانه را = the rent (as the object)
• پرداخت کنیم = we pay

Together: we should pay the rent.

It is built into the verb کنیم.

The ending -یم shows we. Persian often drops subject pronouns when the verb already makes the subject clear.

So:

• کنم = I do
• کنی = you do
• کند = he/she does
• کنیم = we do

That is why Persian does not need ما here, although you could add it for emphasis: اما ما باید...

باید can cover all of those, depending on context.

In this sentence, because paying rent is an obligation, natural English choices are:

• have to
• need to
• must

So اما باید اجاره خانه را زود پرداخت کنیم can feel like but we have to pay the rent soon. It does not always sound as strong or dramatic as English must.

After باید, Persian usually uses a subjunctive-style verb form.

Here, the verb is پرداخت کردن = to pay, and the conjugated part is کنیم. So:

• باید پرداخت کنیم = we must / should pay

This is a very common pattern in Persian.

Also, because پرداخت کردن is a compound verb, Persian often uses کنیم rather than بکنیم in this kind of structure.

Yes. The full verb is پرداخت کردن = to pay.

Many Persian verbs are made of:

• a noun or verbal element
• plus a light verb such as کردن, شدن, دادن, etc.

Here:

• پرداخت = payment / paying
• کردن = to do

Only the light verb changes for tense and person, so you get کنیم.

A more compact alternative you may also hear is بپردازیم, but پرداخت کنیم is perfectly normal and very common.

زود literally means early, quickly, or soon, depending on context.

In this sentence, it means soon or promptly:

• زود پرداخت کنیم = pay soon / pay without much delay

So it is not about doing the action fast in a physical sense; it is about not waiting too long.

Yes, it could be left out in everyday speech.

The full formal written form is:

• نیامده است

In conversation, people very often say:

• نیامده

Both mean the same thing here. Keeping است sounds more formal or careful, which fits standard written Persian.

Persian usually prefers subject-object-verb order, and the main verb tends to come late.

This sentence breaks down like this:

• قبض گاز = subject
• هنوز = adverb
• نیامده است = verb

Then:

• اما = but
• باید = must / have to
• اجاره خانه را = object
• زود = adverb
• پرداخت کنیم = verb

So the overall structure is very Persian: the important verb information comes near the end of each clause.
