إما أن تجتاز المركبة الفحص أو تفشل في الفحص.

إما introduces the first part of an either/or choice. In this sentence, the pattern is:

إما ... أو ...
= either ... or ...

So:

إما أن تجتاز المركبة الفحص أو تفشل في الفحص
means Either the vehicle passes the inspection, or it fails the inspection.

This is a very common structure in Modern Standard Arabic.

Here أن helps introduce a verb after إما. In this pattern, you will often see:

إما أن + present verb ... أو + present verb

So:

• إما أن تجتاز ...
• أو تفشل ...

The أن here is part of a standard formal construction. It is natural in MSA to say:

إما أن تجتاز المركبة الفحص أو تفشل في الفحص

You may notice that أن is not repeated before تفشل. That is normal; Arabic often uses it only in the first half of the pair.

تجتاز comes from the verb اجتاز, which often means to pass, to get through, or to successfully undergo something such as:

• a test
• an exam
• an inspection
• a stage

So اجتاز الفحص means to pass the inspection.

This verb is very common in formal Arabic for passing tests, checks, and procedures. It sounds especially suitable in official or technical contexts.

Because تجتاز can take a direct object.

So in:

تجتاز المركبة الفحص

• المركبة = the subject = the vehicle
• الفحص = the direct object = the inspection

Literally, it is something like the vehicle passes the inspection.

This is similar to English, where pass can also take a direct object:

• pass the test
• pass the exam
• pass the inspection

Because the verb فشل is commonly used with the preposition في when talking about failing at something.

So Arabic naturally says:

• فشل في الامتحان = he failed the exam
• فشلت في الاختبار = she failed the test
• تفشل في الفحص = it fails the inspection

This is different from اجتاز, which usually takes a direct object. So the sentence uses two different verb patterns:

• اجتاز الفحص
• فشل في الفحص

That is completely normal.

Because المركبة is grammatically feminine in Arabic.

Even though a vehicle is not biologically female, many inanimate nouns in Arabic are grammatically either masculine or feminine. مركبة is feminine, so the verb agrees with it:

• تجتاز المركبة
• تفشل المركبة or here تفشل في الفحص

That is why you see تـ at the beginning of both verbs.

A big clue is the ending ـة (taa marbuuTa). Many nouns ending in ـة are feminine.

So:

• مركبة = feminine
• therefore the verb is feminine singular:
  • تجتاز
  • تفشل

This is one of the most useful patterns for learners, though there are some exceptions elsewhere in the language.

In careful fully vocalized Arabic, it would typically be:

إمّا أن تَجتازَ المركبةُ الفحصَ أو تَفشَلَ في الفحصِ

A few things are happening here:

• المركبةُ has -u because it is the subject.
• الفحصَ after تجتاز has -a because it is a direct object.
• الفحصِ after في has -i because it comes after a preposition.
• The verbs after أن and in the coordinated structure are often in the subjunctive:
  • تجتازَ
  • تفشلَ

In normal unvocalized writing, these endings are usually not shown.

Yes, Arabic could sometimes avoid repetition if the meaning is obvious, but repeating الفحص makes the sentence clearer and more balanced.

So:

تجتاز المركبة الفحص أو تفشل في الفحص

is very natural because each half is complete and explicit.

The repetition also works well in formal, instructional, or technical language, where clarity is important.

Usually yes, in meaning and function. It presents two alternatives.

But in real Arabic usage, the exact style can vary. For example, Arabic may sometimes use just أو without إما if the context already makes the alternative clear. Still, إما ... أو ... is a very standard and clear way to express either/or.

The dictionary forms are:

• اجتاز = to pass, to get through
• فشل = to fail

The forms in the sentence are present-tense forms agreeing with المركبة:

• تجتاز = it passes / it will pass
• تفشل = it fails / it will fail

Because the subject is feminine singular, both verbs begin with تـ.

It can often be understood as either, depending on context.

The Arabic present tense can express:

• present meaning
• future meaning
• general statements

So this sentence could mean:

• Either the vehicle passes the inspection or fails the inspection
• or Either the vehicle will pass the inspection or fail the inspection

In a context about an upcoming inspection, English would often translate it as future. In a general rule or procedure, English might use the present.

Yes. This is a very reusable pattern:

إما أن + verb + subject/object ... أو + verb ...

For example:

• إما أن يجتاز الطالب الامتحان أو يفشل فيه
  Either the student passes the exam or fails it.

• إما أن تنجح الخطة أو تنهار
  Either the plan succeeds or collapses.

So the sentence is useful not only for this vocabulary, but also as a model for making alternatives in formal Arabic.
