The phonology of Urdu appears to be different enough from that of Hindi because of however artificial phonemes not for instance present in Hindi as they are of Persian derivation WP CFORK simply does not apply because here is not a case of I quote the this page in a nutshell box Articles should not be split into multiple articles just so each can advocate a different stance on the subject since there is no stance to be taken it s just a matter of Urdu phonology being different from Hindi phonology If you want the differences between Urdu and Hindi phonology to be more prominently highlighted than they are now you can as I said do it yourself you can t expect to force others to add content surely As to code switching for other languages this seems to be tackled by having a separate article about the common code switching mixtures Spanglish and so on and linking them in the See also sections so feel free to do this if you want for what I m concerned
