However, I am curious to know why some languages like Persian, Turkish, Chinese have complex morphology system, meanwhile other languages like English have much more simpler morphology system. In other hand, is there any criteria caused such difference like their historical change, their lexicon properties, or their type (Indo-European, or more specific type like Romance)?</div><div><br></div><div>I do not have good linguistic background, so I would be grateful if anyone provide me with some material related to this issue too.</div><div><br></div><div><div apple-content-edited="true">
