TANOFUR (arabi — nafrat kardan, az yaqdigar duri justan), tanofuri quruf, illatisherro guyand, ki dar natijai pay dar ham omadani ovozho (harfho)-i makhrajashon ba ham nazdik ba vujud meoyad. Talaffuzi in ovozho dushvor ast va ba gush sakht merasad. Muvofiqi guftai Roduyoni tanofur du khel meshavad: ovozi (tanofuri huruf) va manavi. Dar tanofuri ovozi ba sababi az yaqdigar dur budani harfho ba zabon ovardani bayt mushkil ast.
Masalan:
Ba qurbi qabri garibon guzar kuni, chi shavad?
In nav tanofurro mualllimon baroi rost kardani zabon (talaffuz)-i kudakon istifoda mebarand.
Navi digari tanofur, ba aqidai Roduyoni, ba robitai manavii misra va baytho aloqamand ast, yane manii baytho yo misraho az yakdigar dur meaftand. In hodisa dar yak misra ham voqe meshavad:
Chu nushi sabuhi, zi mo yod kun!
Aksar adibon az tanosubi bayni ovoz va matlab, mavzu, goya mohirona istifoda karda, sherhoi dilkashu foram guftaand. Az in sheri Mashuchehri tavassuti ovozhoi «kh» va «z» kas ovozi khazovro meshunavad:
Khezedu khaz ored, ki hangomi khazon ast,
Bodi khunuk az jonibi Khorazm vazon ast.
On bargi ravon bin, ki bar on shokhi razon ast,
Guyo ba masal pirahani rangrazon ast.
Dehqon ba taajjub sari angusht gazon ast,
K-andar chamanu bog na gul mondu na gulzor.
