أجل، هذا صحيح.

In this sentence, أجل means yes.

A learner should know that:

• أجل and نعم can both mean yes in Modern Standard Arabic.
• أجل often sounds a bit more formal, bookish, or careful.
• نعم is also standard and is often the more basic, common word learners meet first.

So:

• أجل، هذا صحيح. = Yes, that is correct.
• نعم، هذا صحيح. = also Yes, that is correct.

In everyday spoken Arabic, many dialects use other words for yes, so أجل is mainly something you should recognize and be able to use in formal Arabic.

This is a very common question.

Literally, هذا صحيح means this is correct.

But in Arabic, هذا is often used to refer to:

• something just mentioned
• an idea
• a statement
• a situation being discussed

So even if English naturally says that’s correct, Arabic may use هذا.

This is not strange in Arabic. It is just the normal way to point to the statement or idea under discussion.

You may also sometimes see ذلك صحيح (that is correct), but هذا صحيح is extremely common and natural.

Because Arabic usually does not use a present-tense verb to be in sentences like this.

So:

• هذا صحيح literally looks like this correct
• but it means this is correct

This kind of sentence is called a nominal sentence.

Compare:

• هذا صحيح = This is correct
• هذا كان صحيحًا = This was correct
• هذا سيكون صحيحًا = This will be correct

In the present tense, Arabic usually leaves out is/am/are.

صحيح is masculine because it matches هذا, which is masculine singular.

In Arabic, adjectives agree with what they describe in:

• gender
• number
• definiteness

Here, هذا is masculine singular, so the predicate adjective appears as:

• صحيح = masculine singular

If the subject were feminine, you would normally use:

• هذه صحيحة = This is correct (with a feminine referent)

For example:

• هذه الإجابة صحيحة = This answer is correct

But in هذا صحيح, the expression is referring generally to a statement or idea, and the masculine form is the normal one.

Here, صحيح is an adjective meaning:

• correct
• true
• right
• sometimes valid depending on context

In هذا صحيح, it functions as the predicate of the sentence:

• هذا = subject-like element, this
• صحيح = predicate, correct

So the whole sentence means This is correct.

You will see صحيح in many useful expressions, such as:

• هذا صحيح = That/this is correct
• غير صحيح = incorrect / not true
• هل هذا صحيح؟ = Is this correct?

A simple pronunciation guide is:

• ʾajal, hādhā ṣaḥīḥ

A rough English-friendly guide could be:

• a-jal, haa-dhaa sa-HEEH

A few important sound notes:

• أ at the beginning of أجل is a glottal stop, like the break in uh-oh
• ذ in هذا sounds like th in this
• ص in صحيح is a deep, emphatic s
• ح is a strong breathy sound from deeper in the throat than English h
• ي in صحيح gives the long ee sound

The stress is usually close to:

• ʾA-jal
• HAA-dhaa
• sa-HEEH

Yes, absolutely.

Both are correct in Modern Standard Arabic:

• أجل، هذا صحيح
• نعم، هذا صحيح

The difference is mainly one of tone and style:

• نعم = very common, straightforward yes
• أجل = also yes, but often a bit more formal or literary

So if you are learning MSA, it is useful to know both.

Yes.

You can write it as:

• أجل. هذا صحيح.

or with a comma:

• أجل، هذا صحيح.

Both are fine.

The version with the comma makes it feel like one flowing response:

• Yes, that is correct.

The version with two full stops can sound slightly more separate or emphatic:

• Yes. That is correct.

It is best understood as neutral-to-formal Modern Standard Arabic.

• هذا صحيح is very common and neutral in MSA.
• أجل gives the whole sentence a slightly more formal or written feel.

So this is a very natural sentence in:

• news language
• formal conversation
• interviews
• writing
• classroom Arabic

In many everyday dialect conversations, speakers might choose different words for yes, but the MSA sentence itself is perfectly normal.

Yes.

Depending on context, صحيح can mean:

• correct
• true
• right
• valid
• sometimes even healthy in other contexts

In هذا صحيح, the intended meaning is usually:

• That is correct
• That is true

So the exact English translation depends on the situation, even though the Arabic words stay the same.

Arabic certainly can say ذلك صحيح, but هذا صحيح is often the more natural choice when reacting to something that was just said.

That is because هذا can point to the statement currently in focus, almost like saying:

• this point
• this statement
• what you just said

So although English often prefers that’s correct, Arabic commonly uses هذا صحيح in the same situation.

In other words, the translation may say that, but the Arabic structure does not have to match English word-for-word.
