Bu ürün ucuz; buna ek olarak sağlam.

In Turkish, the verb to be is often omitted in the 3rd person singular present when the predicate is a noun or adjective.

So:

• Bu ürün ucuz = This product is cheap
• Bu ürün sağlam = This product is durable / sturdy

This is completely normal Turkish. If you want a more formal or emphatic version, you can add -dır / -dir / -dur / -dür:

• Bu ürün ucuzdur; buna ek olarak sağlamdır.

But in everyday Turkish, leaving it out is much more common.

Because the subject is already clear. Turkish often leaves out repeated words when they are understood from context.

So in:

• Bu ürün ucuz; buna ek olarak sağlam.

the second part still means:

• Bu ürün sağlam

Repeating bu ürün would be grammatical, but it would sound unnecessarily repetitive.

Literally, it breaks down like this:

• bu = this
• buna = to this / to that
• ek = addition
• olarak = as

So buna ek olarak literally means something like as an addition to this.

In natural English, it works like:

• in addition
• besides that
• what’s more
• additionally

It is a linking expression used to add another point.

Because buna is the dative form of bu.

The pronoun bu becomes:

• bunu = this, as a direct object
• buna = to this
• bunda = in/on this
• bundan = from this

Here, the phrase buna ek olarak uses the dative form, so buna is required.

Also, with bu, şu, and o, Turkish inserts an extra n before some case endings:

• bu + a → buna
• şu + a → şuna
• o + a → ona

Olarak is a very common form in Turkish that often means as or in the role of.

So:

• ek olarak = as an addition / additionally

In this sentence, olarak helps turn ek into a phrase that functions adverbially.

You will see olarak in many other expressions too, such as:

• öğretmen olarak = as a teacher
• genel olarak = generally
• resmî olarak = officially

Here, sağlam describes the product as durable, sturdy, robust, or well-built.

For objects, sağlam usually means something like:

• strong
• solid
• not flimsy
• not easily damaged

Be careful: sağlam can also have other meanings in other contexts. For example, with people it can sometimes mean healthy or sound. But in this sentence, with ürün, it clearly means durable/sturdy.

No, it is a punctuation choice, not a grammar rule.

The semicolon shows that the two parts are closely related but still separate statements:

• Bu ürün ucuz; buna ek olarak sağlam.

You could also write it in other natural ways, for example:

• Bu ürün ucuz, ayrıca sağlam.
• Bu ürün ucuz. Buna ek olarak sağlam.

The semicolon just gives the sentence a slightly more formal, organized feel.

Yes. That is very natural.

For example:

• Bu ürün ucuz; ayrıca sağlam.

This means almost the same thing.

The difference is mainly style:

• ayrıca = shorter, simpler, very common
• buna ek olarak = a bit more formal, a bit more explicit, like in addition to this

So both are correct, but buna ek olarak sounds slightly more polished or written.

Yes, Turkish word order is fairly flexible, especially with linking expressions like buna ek olarak.

You could say:

• Bu ürün ucuz; buna ek olarak sağlam.
• Buna ek olarak bu ürün sağlam.
• Bu ürün ucuz. Buna ek olarak sağlam.

All of these are understandable.

However, the original version is nice because it first gives the main statement, then adds another positive feature.

Yes, absolutely.

• Bu ürün ucuz ve sağlam = This product is cheap and durable

This is simpler and probably the most direct everyday version.

The difference is:

• ucuz ve sağlam simply joins two qualities with and
• buna ek olarak makes the second quality sound like an extra point being added

So the original sentence has a slightly more rhetorical or persuasive tone.

The ğ in Turkish is usually not pronounced like a hard g in English.

In sağlam, it typically lengthens the vowel before it, so it sounds roughly like:

• saalam

More accurately, the first vowel is stretched a bit. So sağlam is approximately pronounced saa-lam.

This is very common in Turkish:

• dağ sounds roughly like daa
• soğuk sounds roughly like so-uk or soo-uk

So when you see ğ, do not pronounce it like the g in go.

Turkish does not use articles the same way English does.

• There is no direct equivalent of the
• bir can sometimes mean a/an, but it is not always needed

Here, bu ürün already means this product, so it is specific enough on its own.

That is why you do not need anything like the before ürün.
