Many of my foreign friends have wrong assumptions about Turkish.
Most people think that Turkish is similar to the languages of Turkey’s neighboring countries or that Turkish is a unique language on its own.
Yet, Turkish is a vast language with mutual intelligibility with many languages of Central Asia.
Turkish is a Turkic Language and is highly similar to other Turkic Languages.
There is a high degree of mutual intelligibility between Turkic Languages and Turkish. The main Turkic Languages are Azerbaijani, Turkmen, Uzbek, Uyghur, Tatar, Kazakh, and Kyrgyz languages.
Moreover, grammar and language structure is nearly the same. For these reasons, some also claim Turkish is not a language but a dialect of Turkic Languages.
Also, many linguists believe that Uralic and Altaic languages have an ancestral connection with Turkic Languages.
Turkish is known to have grammatical similarities between Uralic and Altaic languages but no mutual intelligibility or similar words.
The major languages that Turkish is known to have grammatical similarities are Hungarian, Finnish, Mongolian, Korean, and Japanese.
After Turkic Languages, French, Persian, Greek, and Arabic are the languages that Turkish shares the most words.
Most loanwords are a result of cultural relations, and there is no structural and grammatical similarity between these languages and the Turkish Language.

2. Turkic Languages
Turkish is a Turkic Language and is highly similar to other Turkic Languages.
Oghuz Turks, ancestors of Turkish people in Turkey, migrated from Central Asia to Turkey about 1000 years ago.
Yet, there is still a high degree of mutual intelligibility between Turkish and Central Asian Turkic Languages.
Moreover, Turkic Languages and Turkish share the same grammar and language structure with minor differences.
It is also a popular idea to claim Turkish is not a language but a dialect of Turkic Languages.
Azerbaijani is the closest language to Turkish.
For example, Azerbaijani spoken in Azerbaijan has slight differences from Azerbaijani spoken in Iran. Yet, they are regarded as dialects of each other.
Turkish, spoken in Turkey, also has slight differences from Azerbaijani dialects, but Turkish is regarded as a separate language.
As a native Turkish speaker, when I am speaking with an Azeri, I do not feel like they are speaking a different language, but it is more like a dialect of Turkish.
I can speak a moderate level of Italian and Spanish.
From my own language learning experience, I can say that the differences between Turkish and Turkic languages are similar to the differences between Italian, Spanish, and Portuguese languages.
Yet, some Turkic languages like Azerbaijani and Turkish are even more similar to be categorized as the same language.

3. Altaic Languages – (also called Transeurasian Languages)
According to Transeurasian Language theory, the Turkish Language and all Turkic Languages are related to Japonic, Koreanic, Tungusic, and Mongolic Languages.
These languages definitely have common grammatical, logical, and structural features.
Yet, it is debatable whether these languages share a common ancestry or whether the similarities are the results of cultural exchanges between these languages. source source2
Japanese linguists widely reject Japanese Altaic roots and the Japanese language’s relation to the Korean language. Yet, Japanese has some similar features with Turkish and other Altaic languages.
Japanese has agglutination (adding prefixes to verbs), sentence structure (Subject-Object-Verb), and other grammar similarities.
The Korean language can be more similar to Turkish than Japanese, yet similarities lie primarily in the grammar structures of these languages.
Korean and Turkish also share similar grammatical structures like agglutination, sentence structure, the syntax of adjectives and nouns, and vowel harmony.
4. Uralic Languages and Hungarian Language
Estonian, Hungarian, Finnish, and other Uralic languages have similar grammatical concepts.
For these reasons, some linguists theorize that Turkish and Uralic languages are similar and have a common ancestry.
This theory is widely criticized. Hungary, on the other hand, is a different story.
Hungarians are descendants of the Huns, who were a Turkic Tribe. For these reasons, Hungary is attending the Council of Turkic countries, and Hungary accepts Hungarian to be a Turkic Language.
Yet, Hungarian is the less similar language to Turkish among Turkic Languages and has no mutual intelligibility.

5. Loanwords in Turkish
In the Ottoman Empire Era, the official language was Ottoman Turkish which had many Persian and Arabic words.
The administration language was different from the Turkish that ordinary people speak. This created many socio-political issues.
After the reforms in the 1920s, most loanwords in Ottoman Turkish were abandoned, and the Istanbul street language was adopted as the official language of Turkey.
Today, the Turkish Language still has many loanwords from French, Arabic, Persian, and Greek languages.
Yet, similarities between these languages end here. 86% of the Turkish Language consists of original Turkish words.
Being a Turkic language, Turkish Language origin and grammar are different from Indo-European Languages (French, Persian, and Greek ) and Semitic Languages (Arabic).
Turkish Vocabulary has 6% Arabic, 5% French, 1% Persian, and less than 1% English and Greek Loanwords.
