هذا يناسبني.

A common pronunciation is:

hādhā yunāsibunī

A more learner-friendly breakdown:

• هذا = hā-dhā
• يناسبني = yu-nā-si-bu-nī

A few notes:

• The ذ sound in هذا is like the th in this.
• The long ā sounds like the a in father.
• In normal unvowelled writing, you usually see it as هذا يناسبني without the short vowels.

Word by word:

• هذا = this
• يناسب = suits / is suitable for / fits
• ني = me

So the structure is basically:

this + suits + me

Even if the natural English translation may vary, that is the literal layout.

The verb is يناسب.

Its dictionary form is ناسبَ.

This verb commonly means:

• to suit
• to be suitable for
• to fit (depending on context)

So in هذا يناسبني, the action is suiting/fitting.

In Arabic, verbs in the imperfect/present tense often begin with a prefix that tells you the person.

Here:

• يـ usually marks he / it

So يناسب literally means:

• he suits
• it suits

Since هذا means this, and this is treated as grammatically masculine singular here, the verb appears in the 3rd person masculine singular form:

• هذا يناسبني = this suits me

ـني is an attached object pronoun meaning me.

So:

• يناسب = it suits
• يناسبني = it suits me

This is very common in Arabic. Object pronouns are often attached directly to the verb.

Examples of similar endings:

• يناسبك = it suits you
• يناسبه = it suits him
• يناسبها = it suits her
• يناسبنا = it suits us

هذا is the masculine singular demonstrative: this
هذه is the feminine singular demonstrative: this

So you use هذا when the thing referred to is grammatically masculine, or when you are pointing to something understood as masculine.

Examples:

• هذا الكتاب يناسبني = This book suits me
• هذه الحقيبة تناسبني = This bag suits me

Notice that when the subject is feminine, the verb also changes:

• هذا يناسبني
• هذه تناسبني

Because هذا is grammatically masculine singular.

In Arabic, the verb agrees with the subject in gender and number. So:

• هذا يناسبني = This suits me (masculine)
• هذه تناسبني = This suits me (feminine)

So the choice between يـ and تـ depends on the gender of the subject.

Yes. يناسب is in the imperfect tense, which often covers:

• present
• habitual
• sometimes near future, depending on context

So هذا يناسبني usually means:

• This suits me
• This fits me
• This is suitable for me

The exact English translation depends on context.

It can mean either, depending on context.

Common possibilities:

• هذا يناسبني = This suits me
  for style, choice, plan, schedule, etc.
• هذا يناسبني = This fits me
  for clothes, size, arrangement, etc.
• هذا يناسبني = This works for me

So Arabic ناسب is broader than one single English verb.

The structure is:

• هذا = subject
• يناسبني = verb + object pronoun

So literally:

This suits me.

This is a very normal Arabic pattern. Even though Arabic often allows verb-first sentences, subject-first sentences are also extremely common.

Compare:

• هذا يناسبني = This suits me
• يناسبني هذا = literally Suits me, this / This suits me

Both can occur, but هذا يناسبني is straightforward and very common.

Yes, you can.

• هذا يناسبني
• يناسبني هذا

Both can mean This suits me.

The difference is usually one of emphasis or style:

• هذا يناسبني starts with this, so it highlights the thing.
• يناسبني هذا starts with the verb, which can sound a bit more like This works for me or place more focus on the suitability itself.

For a learner, هذا يناسبني is the safest neutral choice.

The fully vowelled form is usually written:

هٰذا يُناسِبُني

You may also see the first word written simply as هذا without extra marking, which is much more common in everyday texts.

Breakdown:

• هٰذا = hādhā
• يُناسِبُني = yunāsibunī

In ordinary Arabic writing, short vowels are usually omitted, so learners need to infer them.

ناسب is a derived verb, specifically Form III.

Its basic pattern is:

• ناسَبَ → يُناسِبُ

For many learners, the important practical point is simply:

• past: ناسبَ
• present/imperfect: يناسبُ
• meaning: to suit / to be suitable for

You do not need to master the whole derivational system immediately, but it is useful to recognize that this is not a basic three-letter simple verb form.

Yes, depending on what you mean.

For example:

• if you mean This arrangement suits me
• This time suits me
• This option works for me

then هذا يناسبني is very natural.

If you are talking about a masculine noun explicitly, you can also say things like:

• هذا اللون يناسبني = This color suits me
• هذا القميص يناسبني = This shirt fits/suits me

So the sentence works with many kinds of things, not just objects in a narrow sense.

Yes, in a sense.

Arabic verbs already contain person/gender/number information. So يناسب by itself already means something like:

• he suits
• it suits

Then هذا names what that it/this is.

So Arabic does not need a separate word like English it here. The verb form itself carries that information.
