تنتهي المباراة بالتعادل.

A careful pronunciation is:

tan-tahī al-mubārāh bi-t-taʿādul

A more fully grammatical reading with case endings would be:

tan-tahī al-mubārātu bi-t-taʿāduli

A few notes:

• تنتهي = tan-tahī
• المباراة = al-mubārāh in pause, or al-mubārātu with the full case ending
• بالتعادل is pronounced bi-t-taʿādul, because the ل of ال assimilates to ت

Because Arabic very often uses verb–subject word order.

So instead of saying:

• The match ends in a draw

Arabic naturally says:

• Ends the match in a draw

That means:

• تنتهي = the verb, ends
• المباراة = the subject, the match

Even though المباراة comes after the verb, it is still the subject.

Because المباراة is a feminine noun.

In Arabic, a noun ending in ـة is very often feminine, and مباراة ends that way. So the verb has to agree with it.

Here:

• تنتهي = it ends for a feminine singular subject
• the subject is المباراة = the match

So the feminine form is required.

تنتهي is the imperfect form.

In English, that can correspond to different translations depending on context, such as:

• ends
• is ending
• sometimes even a narrative ended, if the context is reporting events in a vivid present style

So grammatically it is the imperfect, but the exact English tense depends on context.

The dictionary form is انتهى.

That verb means:

• to end
• to come to an end
• to finish

Its imperfect form is ينتهي for he/it ends, and with a feminine singular subject it becomes تنتهي.

So the pattern is:

• انتهى = past, ended
• ينتهي = he/it ends
• تنتهي = she/it ends or you end depending on context

Here it means it ends, referring to the match.

Here بـ is the preposition bi-, and in this sentence it gives the sense of:

• in
• with
• by

In natural English, the whole phrase بالتعادل is best understood as:

• in a draw
• as a draw

So تنتهي المباراة بالتعادل means literally something like:

• The match ends with the draw

but idiomatically:

• The match ends in a draw

Because ت is a sun letter.

When ال comes before a sun letter, the ل sound is not pronounced separately. Instead, it assimilates to the following consonant.

So:

• written: التعادل
• pronounced: at-taʿādul

And with the preposition بـ attached:

• written: بالتعادل
• pronounced: bi-t-taʿādul

This is a very common feature of Arabic pronunciation.

This is one of those places where Arabic and English do not match word-for-word.

Arabic often uses the definite article in expressions where English would use:

• a
• no article at all
• or a more idiomatic phrase

So بالتعادل is a natural Arabic expression meaning:

• in a draw
• as a draw

You should learn the whole phrase as a unit:

• تنتهي المباراة بالتعادل = The match ends in a draw

If you fully vocalize the sentence, it is:

تنتهي المباراةُ بالتعادلِ

Why?

• المباراةُ is the subject, so it is nominative
• التعادلِ comes after the preposition بـ, so it is genitive

So:

• المباراةُ = nominative
• بالتعادلِ = preposition + genitive noun

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

Yes.

That would be the past tense:

• انتهت المباراة بالتعادل = The match ended in a draw

The version with تنتهي is imperfect/present-style:

• تنتهي المباراة بالتعادل

Depending on context, it may sound like:

• a general statement
• sports commentary
• a headline style
• a vivid narrative

So both are possible, but they are not exactly the same tense.

Yes. التعادل is a very common Modern Standard Arabic word for:

• a draw
• a tie

It comes from a root connected with equality or being level, which fits the sports meaning well.

So in match reports, phrases like these are very common:

• انتهت المباراة بالتعادل = The match ended in a draw
• تعادل الفريقان = The two teams drew / tied

No direct object is present here.

The structure is:

• تنتهي = verb
• المباراة = subject
• بالتعادل = prepositional phrase describing the result

So this is not the match ends something. It is simply:

• the match ends and then
• in a draw

The phrase بالتعادل tells you the manner or result of the ending.
