موظف المحطة يعلن عن تأخر القطار.

A fully vowelled reading is:

مُوَظَّفُ الْمَحَطَّةِ يُعْلِنُ عَنْ تَأَخُّرِ الْقِطَارِ

A common transliteration is:

muwaẓẓafu l-maḥaṭṭati yuʿlinu ʿan taʾakhkhuri l-qiṭāri

A natural word-by-word pronunciation guide for an English speaker:

• مُوَظَّف = mu-waẓ-ẓaf
• الْمَحَطَّة = al-ma-ḥaṭ-ṭah
• يُعْلِن = yuʿ-lin
• عَنْ = ʿan
• تَأَخُّر = ta-ʾakh-khur
• الْقِطَار = al-qi-ṭaar

A few sounds to notice:

• ظ is an emphatic sound, often approximated by learners as a heavy z.
• ح is a strong breathy h from the throat.
• ع does not exist in English; many beginners just pause slightly or approximate it at first.

Because موظف المحطة is an iḍāfa construction, often called a possessive or noun-link construction.

It literally means something like:

• employee of the station

In Arabic iḍāfa:

• the first noun usually does not take الـ
• the second noun can be definite, and if it is definite, the whole phrase becomes definite

So:

• موظف المحطة = the station employee
• not an employee of a station

This is one of the most important patterns in Arabic.

It is definite.

Even though موظف itself does not have الـ, the whole iḍāfa phrase becomes definite because the second noun is definite:

• المحطة = the station

So:

• موظف المحطة = the station employee

If it were indefinite, you might see something like:

• موظفُ محطةٍ = an employee of a station

So definiteness in iḍāfa depends on the second noun.

The sentence is:

• موظف المحطة = the subject
• يعلن عن تأخر القطار = the predicate

So the full structure is roughly:

• [The station employee] [announces the train’s delay].

Because the sentence begins with a noun phrase, it is analyzed as a nominal sentence in Arabic grammar, even though the predicate contains a verb.

More specifically:

• موظفُ = subject head noun
• المحطةِ = second part of the iḍāfa
• يعلنُ = verb in the predicate
• عن تأخر القطار = prepositional phrase/complement attached to the verb

In Modern Standard Arabic, the present tense can express several ideas, including:

• something happening now
• a habitual action
• a general present statement

So يعلن can mean:

• is announcing
• announces

In this sentence, the exact English translation depends on context. In a station setting, it could mean either:

• The station employee is announcing the train’s delay or
• The station employee announces the train’s delay

Arabic often leaves that distinction to context.

Because the verb أعلن / يعلن is commonly used with the preposition عن when meaning to announce / declare / report about something.

So:

• يعلن عن تأخر القطار = he announces the train’s delay

This is a common verb-preposition pairing that learners simply need to memorize.

Compare:

• أعلن عن الخبر = he announced the news
• أعلن عن القرار = he announced the decision

Arabic verbs often require particular prepositions, and they do not always match English patterns exactly.

Here تأخر is a verbal noun (called a maṣdar), not a finite verb.

It means:

• delay
• lateness
• being late

It comes from the verb:

• تأخر = to be late / to be delayed

So:

• تأخر القطار literally = the delay of the train
• more naturally in English = the train’s delay

This is very common in Arabic: instead of using a full clause like that the train is late, Arabic often uses a verbal noun.

القطار has الـ, so it means the train.

In context, this usually refers to a specific train known to the speaker and listener, such as the train currently expected at the station.

Inside the phrase:

• تأخر القطار = the train’s delay

This is also an iḍāfa:

• تأخر = delay
• القطار = the train

Because القطار is definite, the whole phrase تأخر القطار is definite as well.

Because everyday printed Arabic usually omits short vowels and case endings.

The unvowelled sentence is written:

موظف المحطة يعلن عن تأخر القطار

But in full grammatical form it would be:

مُوَظَّفُ الْمَحَطَّةِ يُعْلِنُ عَنْ تَأَخُّرِ الْقِطَارِ

The endings are:

• موظفُ = nominative, because it is the subject
• المحطةِ = genitive, because it is the second term of iḍāfa
• يعلنُ = indicative present
• عن = preposition
• تأخرِ = genitive after the preposition عن
• القطارِ = genitive as second term of iḍāfa

Learners often do not see these endings in ordinary text, but they still matter in formal grammar.

Yes. You could also say:

يعلن موظف المحطة عن تأخر القطار

This means essentially the same thing:

• The station employee announces the train’s delay

The difference is mostly one of style and focus:

• موظف المحطة يعلن... puts the noun phrase first, which can feel a bit more topic-focused: The station employee, he announces...
• يعلن موظف المحطة... is a more straightforward verbal sentence: The station employee announces...

Both are normal in MSA.

By itself, محطة means station and can refer to different kinds of stations depending on context:

• train station
• bus station
• broadcast station
• stop/station in a general sense

But because the sentence also mentions القطار (the train), the natural interpretation here is:

• the station employee at a train station

So context tells you which kind of station is meant.

Yes, Arabic could express the idea differently, for example:

• يعلن موظف المحطة أن القطار متأخر
  = The station employee announces that the train is late

That version uses:

• أن = that
• القطار متأخر = the train is late

The original sentence, however, uses a noun phrase:

• عن تأخر القطار = about the train’s delay

Both are natural, but the original version is especially compact and formal-sounding, which is very common in MSA.
