هذا القول واضح.

In Arabic, the verb to be is usually not expressed in the present tense.

So هذا القول واضح literally looks like this statement clear, but it means:

• This statement is clear
• This saying is clear

If you wanted a past tense, you would use a verb such as كان:

• كان هذا القول واضحًا = This statement was clear

Because هذا القول means this statement / this saying.

In Modern Standard Arabic, when a demonstrative like هذا is followed by a noun in this way, that noun is normally definite, so it usually takes الـ.

Compare:

• هذا القول = this statement
• هذا قولٌ = this is a statement / this is a saying

So the presence or absence of الـ changes the structure and meaning.

القول comes from the root ق-و-ل, which is connected with speaking and saying.

Depending on context, قول can mean:

• saying
• statement
• utterance
• remark
• sometimes even opinion or claim

In this sentence, statement or saying is a natural translation.

Because here واضح is the predicate of the sentence, not an adjective directly attached to القول.

So:

• هذا القول واضح = This statement is clear

But if you wanted clear to directly modify statement, you would make it definite too:

• القول الواضح = the clear statement

This is an important Arabic distinction:

• definite noun + indefinite adjective form can signal a complete sentence
• definite noun + definite adjective gives a noun phrase

So واضح here is best understood as is clear, not just clear attached to the noun.

It is an adjective in form, meaning clear or obvious.

But in this sentence it is functioning as the predicate of a nominal sentence.

So:

• as an adjective: قولٌ واضحٌ = a clear statement
• as a predicate: القول واضحٌ = the statement is clear

In هذا القول واضح, it is the second use.

Because قول is a masculine singular noun.

In Arabic, demonstratives must agree with the noun in gender and number:

• هذا = this for masculine singular
• هذه = this for feminine singular

So:

• هذا القول = this statement
• if the noun were feminine, you would say something like هذه العبارة = this expression/phrase

In fully vocalized Arabic, the sentence is:

• هٰذا القَوْلُ واضِحٌ

or commonly written without extra marks:

• هذا القولُ واضحٌ

The endings are:

• القولُ: nominative, because it is part of the subject/topic side of the sentence
• واضحٌ: nominative, because it is the predicate of the nominal sentence

A beginner-friendly way to think of it is:

• هذا القول = the thing being talked about
• واضح = what is being said about it

In normal pause pronunciation, many speakers would drop the final case vowels, so it may sound more like:

• hādhā al-qawl wāḍiḥ

A careful pronunciation is:

• hādhā al-qawlu wāḍiḥun

A few pronunciation notes:

• هذا = hādhā
• ق in القول is a deep q sound, not an English k
• aw in qawl sounds somewhat like the vowel in cow
• واضِح = wāḍiḥ
• ḍ is an emphatic d
• ḥ is a strong breathy h sound from the throat

Also, ق is a moon letter, so the ل of الـ is pronounced clearly:

• al-qawl, not aq-qawl

For a learner, the easiest approach is to treat هذا القول as one unit meaning:

• this statement
• this saying

That is enough for understanding and using the sentence.

In more traditional grammar, you may sometimes see a more detailed analysis where:

• هذا is treated as the main starting element
• القول is treated as an explanatory noun or apposition

But at the practical learning level, it is perfectly fine to understand the phrase simply as this statement.

Yes. واضح has a range of meanings, including:

• clear
• plain
• obvious
• evident

So depending on context, this sentence could also be translated as:

• This statement is obvious
• This saying is plain
• This claim is clear

The best English choice depends on context.

Yes. For example:

• القول واضح = The statement is clear
• هذا قول واضح = This is a clear statement

These are similar, but not identical:

• هذا القول واضح = This statement is clear
• هذا قول واضح = This is a clear statement

That difference is useful because it shows how Arabic handles definiteness and sentence structure very precisely.
