Comparing English and Turkish Sentence Classifications

Updated: Dec 14, 2022

English and Turkish rely on the syntax and grammar of sentences, clauses, and phrases to create narratives. Just as a phrase, a clause is a group of related words. However, unlike a phrase, a clause has both a subject and a verb.

Subject & Predicate

Whether it is a Turkish or an English clause, its core is the combination of one subject (S) and one predicate (P).

The subject answers the questions who or what and names the “do-er” or “be-er” of the sentence. The subject is typically a noun or a noun phrase, including all subject modifiers: e.g., adjectives or numerals.

The predicate is, essentially, everything in the clause that is not the subject.

A predicate consists of the verb (action) and all the words that modify that verb, including:

• Prepositions

• Direct and indirect objects

• Object modifiers and complements

• Adverbials

For example:

İsveçli zengin, bu anlaşmayı, bilgiç şefkati, fedakâr dostluğu yavaş yavaş derisinde duymağa başlamıştı.
Ahmet Hamdi Tanpınar, Huzur

The rich Swede was gradually sensing in his flesh this understanding, her wise compassion, and her generous companionship.

The predicate is made up of at least one finite verb, the action of which is performed by the subject. (In a sentence, the verb that agrees with the subject, i.e., expresses the subject's action, is called finite.)

The difference between finite verb and non-finite verb is important for understanding the logic behind the classification of sentences.


Subject & Predicate in English

English sentences MUST have subjects, even if subjects are not overtly expressed within sentences.

For an English sentence having a subject is essential so much so that a dummy subject (it or there) or an indefinite pronoun (one) must sometimes be introduced:

It is raining.
There is a house over there.
One has to be careful when handling poisons.

Subjects are usually implied in imperative sentences:

[You] Listen!
[You] Come over please.

Subjects may be ellipted in an informal context:

[I’ll] See you soon.

However expressed, the subject is one of the two primary constituents of the English sentence.


Subject & Predicate in Turkish

Just like an English sentence, a simple Turkish sentence consists of two constituents, the verb and the subject, and, as in English, a Turkish clause is defined by expressing a complete thought:

Savaş sona erdi.
The war is over.

Hava güzel.
The weather is fine.

However, unlike English verbs, Turkish verbs agree with the subject in person and number. In other words, a Turkish sentence often “hides” its subject in the verb’s suffix markings (even though, it may still remain ambiguous and depending on the context):

Ödevimi bitirdim.
I have completed my homework.

Kitaplarını satmışlar.
They sold their books.

As such, typologically, Turkish is a null-subject and pro-drop (pronoun-dropping) language. Turkish subjects do not have to be explicitly expressed or, in some cases, even stated.

For example, a Turkish impersonal passive sentence, whose verb is intransitive and in passive voice, doesn’t have a grammatical subject:

Do not enter.

Although one of the two important constituents of a sentence, Turkish subject is often omitted or implied. What’s more, some Turkish sentences do not have any grammatical subjects.

While English sentence must have both subject and verb to make sense, for the Turkish sentence to be meaningful, it is sufficient to have just the verb, without an explicit subject.

Let's Compare!




Finite Verbs vs. Nonfinite Verbs (Verbals)

Structurally, whether it is English or Turkish, all clauses are either finite or nonfinite, which means they either have finite or nonfinite verbs, respectively.

A finite verb agrees with the (nominative) subject of a simple declarative sentence, i.e., in the subject’s gender, person, number, tense, aspect, mood, and voice markings. Finite verbs are able to make an assertion:

Yazar kitaplar yazar / yazdı.
The author writes / wrote books.

A nonfinite verb is marked with a non-nominative and non-tensed marking (in English) or a subordinating suffix (in Turkish), and they cannot make an assertion:

yazar kitap yazarken
the author writing a book…

yazar hakkında yazılan bu kitap
written about the author, this book…

Nonfinite verbs are products of the so-called nominalization or relativization process. Such process creates from verb stems verbal nouns, adjectivals, and adverbials.

In English, verbals act as reduced verbalized forms. As such, they cannot form independent sentences. As a subordination strategy, the use of verbals is less common than the use of subordinating conjunctions. Dependent sentences formed using verbals are called reduced (subordinate) clauses.

In Turkish, the use of verbals is the principal subordination device, and, just as in English, verbal sentences are always subordinate.

While a finite verb can occur in both independent and dependent clauses (more in English than in Turkish), a nonfinite verb can occur ONLY in a dependent clause.

Nonfinite verbals are especially important in Turkish as the major device for linking clauses to form complex sentences. Although Turkish allows for using finite verbs in dependent clauses (such as ki-clauses, diye-clauses, etc.), nonfinite dependent clauses are much more numerous and, in general, more widely used in literary Turkish.


Independent vs. Dependent Clause: Definitions

In both English and Turkish, the two basic types of clauses are independent and dependent clauses, with the former expressing a complete thought and, thus, being able to stand alone as a sentence.

👉 A dependent clause, however, is an incomplete sentence, relying on the information from a related independent (main) clause to complete a thought.

👉 When independent and dependent clauses are combined in a sentence, they are referred to as main and subordinate clauses, respectively. A subordinate clause can have its own dependent clause, in which case it would be called a matrix clause, and its dependent clause is called an embedded clause.


English Clause vs. Turkish Clause: Main Definitions

👉 In English, by definition, having a subject and a finite verb is sufficient for a clause to make sense. As such, it can stand alone as an independent clause:


👉 In Turkish, however, subjects are often dropped. As a pro-drop (pronoun-dropping) and null-subject language with a highly inflected verbal morphology, Turkish furnishes its finite verbs with the subject’s person and number.


While English clause requires both Subject and Predicate to make sense, Turkish clause needs only Predicate: for example, Gittim (I left) is a single word-sentence. Moreover, Turkish allows also for impersonal sentences: for example, Sıcaktı (It was hot).


Although the classification of sentences is still an unsettled matter in the Turkish syntax school, as opposed to the more well-established English school, the most common Turkish model I have encountered has one independent clause with one subject and one finite verb defined as a simple or basit sentence.

👉 Two independent clauses joined together form one compound sentence or sıralı cümle. If one independent clause and one dependent clause are joined together, they form one complex or birleşik sentence. If two independent clauses and at least one dependent clause are joined together, they form one compound-complex or karmaşık birleşik (sıralı birleşik) sentence.

👉 The complex (birleşik) group is further divided into several subgroups, depending on the type of the dependent clause used (specifically whether the verb is finite or nonfinite).

👉 The compound (sıralı) group is also divided into its own subgroups, depending on whether independent clauses are lexically or morphologically or just semantically related and whether the linking between the clauses is syndetic (using both conjunction and punctuation) or just asyndetic (using punctuation only).


Classification of English Sentences: Four Common Types

English sentences are divided into 4 groups:






In more detail:


In English, a sentence can be SIMPLE despite having internal compound constructions such as compound subjects, predicates, objects of prepositions, or others.

For example, all these sentences are considered SIMPLE in English:

COMPOUND PREDICATE (or shared subject):

The hotel boasts a gourmet restaurant, offers a range of sports facilities, and provides other convenience amenities.

I enjoy tennis, don’t like soccer, and can play basketball if needed.

COMPOUND AUXILIARY VERBS (shared subject + verb + object):

You can, must, and will tell us.

COMPOUND SUBJECTS (or shared predicate):

You, your sister, and I can sit together at my desk.

COMPOUND adverbials (shared subject + verb):

The company may have branches in London, New York, and Moscow.

COMPOUND OBJECT COMPLEMENTS (shared subject + verb):

I argued for implementation of the report, in favor of the new changes, and against any further discussion.

COMPOUND COMPLEMENT CLAUSES (shared subject + verb + object):

The reason probably lies in the facts that the Intelligence Service is rather despised, that the individual members change rapidly and are therefore inexperienced, and that they feel bound to put their own special interests first.

​In Turkish, however, the main difference would be sentences with COMPOUND PREDICATE or COMPOUND AUXILIARY VERBS (as Turkish does not have them, they would be part of main verbs):

Otel, bir gurme restoranına sahiptir, çeşitli spor tesisleri sunmaktadır ve diğer kolaylıklar sağlamaktadır.

Three predicates share the same subject Complex Sentence

Tenisten hoşlanırım, futboldan hoşlanmam ve gerekirse basketbol oynayabilirim.

Three predicates share the same subject Complex Sentence

Bize söyleyebilirsin, söylemek zorundasın ve söyleyeceksin.

Three clauses with the same subject Complex Sentence

There are three types of SIMPLE sentences:

• NOMINAL SENTENCE: The elves were good workers.

• ADJECTIVAL SENTENCE: The elves were unhappy with Santa.

• VERBAL SENTENCE: The elves complained about Santa.


​By definition, a simple sentence is an independent clause (with NO dependent clauses), which has ONE subject and ONE predicate.

By definition, a complex sentence consists of an independent clause and at least one dependent (subordinate) clause, together having TWO subjects and TWO predicates.

​A dependent clause may be:

1. Noun (nominal) clause

2. Adjective (relative) clause

3. Adverb (adverbial) clause

Let’s add a noun clause to an independent clause.

Here are 3 examples of sentences with noun clause (in bold):

1. that students enjoy grammar proves my point noun clause is a subject

2. I believe that students enjoy grammar ⇒ noun clause is an object

3. My point is that students enjoy grammar ⇒ noun clause is a subjec tcomplement

Example 1 has a main clause and a subordinate (noun) clause, so it should be a COMPLEX sentence. However, it has only ONE subject and ONE predicate, which should make it a SIMPLE sentence. So, which one is it? How to categorize a clause whose subject is structured as a dependent clause?

The answer is: NO IDEA. Language textbooks are split. Some define any sentence that has a dependent clause as COMPLEX, regardless of the latter’s role in the structure of the sentence's core. Others insist that a COMPLEX sentence must have a main and a dependent clauses. All seem to agree that subject clauses are special.



The elves were unhappy with Santa, and the reindeer were considering a class-action lawsuit.


where a DEPENDENT clause may be:


That the elves were unhappy with Santa was no secret.


The elves, who were unhappy with Santa, complained to the reindeer.

  • ADVERB (ADVERBIAL) Sentence:

The elves were unhappy with Santa because they had to work during the Christmas season.


The elves were unhappy with Santa, and the reindeer were considering a class-action lawsuit because Rudolph got preferential treatment.

To summarize:


Classification of Turkish Sentences: Four Groups of Sentences

Turkish sentences can be divided into 4 groups as well:




IV. COMPOUND-COMPLEX (sıralı birleşik / karmaşık birleşik) Group = DEPENDENT + INDEPENDENT + INDEPENDENT


I. SIMPLE (basit) Group = PREDICATE = INDEPENDENT, which may be one of the four types:


Sokağın sonundaki ayakkabı tamircisi, bu kasabadaki en eski ve köklü zanaatkârlardan birisidir.
The cobbler at the end of the street is one of the oldest and most established artisans in this town.
