تسجيل الوصول اليوم.

Arabic often allows very short verbless expressions, especially in schedules, signs, labels, reminders, and app interfaces.

So تسجيل الوصول اليوم can be understood as a compact phrase like:

• check-in today
• the check-in is today

In normal present-tense nominal sentences, Arabic often omits the verb to be anyway. So a learner should not expect an explicit word for is here.

تسجيل is a verbal noun (called a maṣdar) from the verb سجّل meaning to register, to record, or to log.

So تسجيل can mean things like:

• registering
• recording
• registration

In this phrase, it is the first part of the fixed expression تسجيل الوصول, which means check-in.

الوصول literally means arrival or reaching/arriving. It comes from the verb وصل meaning to arrive or to reach.

So literally, تسجيل الوصول is something like:

• registration of arrival
• arrival registration

But in natural travel-related Arabic, this is the standard expression for check-in.

This is one of those cases where the literal meaning helps you understand the structure, but the natural English equivalent is a fixed term.

Yes. تسجيل الوصول is an iḍāfa construction, which is often called a possessive or noun-linking structure.

Structure:

• تسجيل = registration
• الوصول = the arrival

Together:

• تسجيل الوصول = check-in / literally registration of arrival

A key rule of iḍāfa is that the first noun usually does not take الـ. That is why you see تسجيل and not التسجيل here.

That is because of the iḍāfa structure.

In an iḍāfa:

• the first noun usually has no الـ
• the second noun can be definite or indefinite
• the definiteness of the whole phrase is controlled by the second noun

So:

• تسجيل الوصول = literally the registration of the arrival

Even though the structure is formally definite because of الوصول, English often translates this kind of expression more naturally as just check-in, without forcing a the.

اليوم means today, and here it functions as an adverb of time.

It tells you when the check-in happens.

So in this phrase:

• تسجيل الوصول = check-in
• اليوم = today

In a fully vocalized form, it would often be understood as اليومَ with an accusative ending, because words of time often function as adverbials in Arabic.

A careful MSA pronunciation would be:

tasjīl al-wuṣūl al-yawm

A few notes:

• تسجيل = tasjīl
• الوصول = al-wuṣūl
• اليوم = al-yawm

Helpful pronunciation points:

• ج in MSA is often taught as a j sound, though regional pronunciation varies.
• ص in الوصول is an emphatic s.
• ī in تسجيل is a long vowel.
• ū in الوصول is also a long vowel.

In normal Arabic writing, short vowels and case endings are usually not written.

So تسجيل الوصول اليوم is the normal unvocalized spelling.

A possible fully vocalized reading is:

تَسْجِيلُ الوُصُولِ اليَوْمَ

Why these endings?

• تسجيلُ: nominative, as the main noun of the expression
• الوصولِ: genitive, because it is the second term of the iḍāfa
• اليومَ: accusative, because it functions as an adverb of time

That said, in a short heading or interface label, native texts often leave all of this unmarked.

It can function as either, depending on context, but most often it feels like a compact phrase or label rather than a full textbook-style sentence.

For example, in an app, hotel notice, or travel schedule, تسجيل الوصول اليوم would naturally read as something like:

• Check-in today
• Today is check-in
• Check-in is today

So grammatically it can be understood elliptically, but stylistically it is very common for Arabic to be this concise in practical contexts.

Yes, تسجيل الوصول is a real and standard Modern Standard Arabic expression for check-in, especially in formal contexts such as:

• airports
• hotels
• travel websites
• official notices

It is a normal MSA term, not just a classroom invention.

In more colloquial settings, some speakers may also use borrowed English terms, but تسجيل الوصول is absolutely standard and widely understood.

If you want something less compressed and more obviously sentence-like, you could say:

• موعد تسجيل الوصول اليوم = The check-in time/date is today
• يكون تسجيل الوصول اليوم = The check-in is today

But in many real contexts, the shorter تسجيل الوصول اليوم is more natural because Arabic often prefers concise informational phrasing.
