The letters ', ', and " are available only in Azerbaijani for sounds which do not exist as separate phonemes in Turkish. Northern Azerbaijani, unlike Turkish, respells foreign names to conform with Latin Azerbaijani spelling, e.g. Bush is spelled ' and Schröder becomes '. Hyphenation across lines directly corresponds to spoken syllables as in other Turkic languages. Some samples include:  Secular: Invoking deity:  Azerbaijani has informal and formal ways of saying things. This is because there is a strong tu-vous distinction in Turkic languages like Azerbaijani and Turkish (as well as in many other languages). The informal "you" is used when talking to close friends, relatives, animals or children. The formal "you" is used when talking to someone who is older than you or someone for whom you would like to show respect (a professor, for example). As in many Turkic languages, personal pronouns can be omitted, and they are only added for emphasis. Azerbaijani has a phonetic writing system, so pronunciation is easy: most words are pronounced exactly as they are spelled in the modern Azerbaijani alphabet. For numbers 11–19, the numbers literally mean "10 one, 10 two" and so on. Greater numbers are constructed by combining in tens and thousands larger to smaller in the same way, without using a conjunction in between.
