[3] The Tanzimât era (1839–1876) saw the application of the term "Ottoman" when referring to the language[4] (لسان عثمانی lisân-ı Osmânî or عثمانلیجه Osmanlıca); Modern Turkish uses the same terms when referring to the language of that era (Osmanlıca and Osmanlı Türkçesi).

Historically, Ottoman Turkish was transformed in three eras: In 1928, following the fall of the Ottoman Empire after World War I and the establishment of the Republic of Turkey, widespread language reforms (a part in the greater framework of Atatürk's reforms) instituted by Mustafa Kemal Atatürk saw the replacement of many Persian and Arabic origin loanwords in the language with their Turkish equivalents.

At first, it was only the script that was changed, and while some households continued to use the Arabic system in private, most of the Turkish population was illiterate at the time, making the switch to the Latin alphabet much easier.

Table below lists nouns with a variety of phonological features that come into play when taking case suffixes.

These words are to serve as references, to observe orthographic conventions: Table below shows the suffixes for creating possessed nouns.

Examples below : Below table shows the positive conjugation for two sample verbs آچمق açmak (to open) and سولمك sevilmek (to be loved).

This consists of adding a Persian or Arabic active or passive participle to a neuter verb, to do (ایتمك etmek) or to become (اولمق olmaq).

Generally, the verbs 'to exist' and 'to have' are expressed using what's called an existential copula, the word وار var.

The verb 'to have' is expressed in the same way, except that the object noun will take a possessive pronoun, producing sentences that will literally mean "there exists house of mine".

Below table is a sample from the verb تپمك tepmek meaning 'to kick', whose root (which is also 2nd person imperative) is تپ tep.

[11][12][13] The conservation of archaic phonological features of the Arabic borrowings furthermore suggests that Arabic-incorporated Persian was absorbed into pre-Ottoman Turkic at an early stage, when the speakers were still located to the north-east of Persia, prior to the westward migration of the Islamic Turkic tribes.

From the early ages of the Ottoman Empire, borrowings from Arabic and Persian were so abundant that original Turkish words were hard to find.

For example, a scribe would use the Arabic asel (عسل) to refer to honey when writing a document but would use the native Turkish word bal (بال) when buying it.
