مسار الهروب واضح تماما.

Because Arabic often uses a nominal sentence in the present tense, with no separate verb meaning is/are.

So:

• مسار الهروب = the escape route
• واضح تماما = completely clear

Together, they mean The escape route is completely clear.

If you wanted a past or future meaning, Arabic would normally use a verb:

• كان مسار الهروب واضحًا تمامًا = The escape route was completely clear

It is a nominal sentence (جملة اسمية), which means it begins with a noun rather than a verb.

Its two main parts are:

• مسار الهروب = the subject/topic
• واضح تماما = the predicate/comment

So the structure is:

• [subject] + [description]

Very common in Arabic.

This is an iḍāfa construction, often called a genitive construction.

• مسار = route/path
• الهروب = the escape / escaping

When two nouns are put together like this, the first noun is linked to the second:

• مسار الهروب = route of escape / escape route

A few important rules of iḍāfa:

1. The first noun usually does not take ال
2. The second noun can be definite or indefinite
3. If the second noun is definite, the whole phrase is definite

Because الهروب has ال, the whole phrase مسار الهروب is understood as definite: the escape route.

Because in an iḍāfa phrase, the first noun normally does not take الـ.

So you get:

• مسار الهروب = the escape route

Not:

• المسار الهروب ❌

The definiteness comes from the second noun:

• مسار هروب = an escape route or route of escape
• مسار الهروب = the escape route

Here واضح is the predicate adjective of the sentence, not part of the noun phrase.

In Arabic nominal sentences, when a definite subject is followed by an adjective-like predicate, that predicate is usually indefinite:

• البيت كبير = The house is big
• الطريق طويل = The road is long
• مسار الهروب واضح = The escape route is clear

If you said الواضح, it would usually change the structure and meaning, rather than simply mean is clear.

Because it agrees with مسار, which is a masculine singular noun.

• مسار = masculine singular
• therefore واضح = masculine singular

If the noun were feminine, the adjective would also be feminine:

• الخطة واضحة = The plan is clear

So here:

• مسار الهروب واضح = correct
• مسار الهروب واضحة = incorrect

تماما means completely, totally, or entirely.

So:

• واضح = clear
• واضح تماما = completely clear / perfectly clear

It functions as an adverb, strengthening the adjective.

You will often see تمامًا used this way:

• مفهوم تماما = completely understood / perfectly clear
• صحيح تماما = absolutely correct

A fully vowelled version is:

مَسارُ الهُروبِ واضِحٌ تَمامًا

Here is what is happening grammatically:

• مَسارُ: subject, so it is in the nominative
• الهُروبِ: second term of the iḍāfa, so it is in the genitive
• واضِحٌ: predicate, also nominative
• تَمامًا: adverb-like accusative form

In normal everyday writing, these short vowels are usually omitted.

It is pronounced approximately:

al-hurūb

The ه in الهروب is a moon letter, not a sun letter, so the ل of الـ is pronounced clearly.

So:

• الهروب = al-hurūb

Compare with a sun-letter word, where the l assimilates:

• الشمس = pronounced ash-shams

But here there is no assimilation.

الهروب comes from the root ه ر ب, which is connected with fleeing or escaping.

Related forms include:

• هَرَبَ = he fled / escaped
• يَهْرُبُ = he flees / is escaping
• هُروب = fleeing / escape

So الهروب in this sentence is a verbal noun or abstract noun meaning escape.

Yes, often you could, depending on context.

Both can mean something like escape route, but there is a slight nuance:

• طريق = road, way, route
• مسار = path, course, track, route

مسار can sound a bit more like a defined path or course, while طريق is often more general and very common.

So both are possible, but مسار الهروب may sound a bit more specific or formal in some contexts.

Because here واضح is not describing مسار inside the noun phrase. It is the predicate of the whole sentence.

Compare these two ideas:

1. مسار الهروب الواضح
   = the clear escape route
   Here الواضح is an adjective modifying the noun phrase.

2. مسار الهروب واضح
   = the escape route is clear
   Here واضح is the predicate.

So the same word can behave differently depending on structure.

Yes, somewhat. The normal straightforward order is:

مسار الهروب واضح تماما

This presents the topic first, then says something about it.

You may sometimes see different word orders for emphasis, but this version is the most neutral and standard for a learner.

A natural transliteration would be:

masāru l-hurūbi wāḍiḥun tamāman

Or, without case endings, as learners often see it:

masār al-hurūb wāḍiḥ tamāman

Both help, but remember that transliteration is only a guide. The Arabic spelling is the most important thing to learn.
