Comments:VEWT 504, EDT 507-508, Лексика 574-575. In general we agree with Doerfer's arguments (TMN 2, 632-642: the Turkic word is the source of Persian tūmān '10000', not vice versa, although in some cases the word was borrowed back into Turkic (in particular: Az. tümän, Khal. timän 'a Persian coin', KBalk., Kum. tümen '10 roubles'); the Tokharian word, whose IE source is highly dubious, is most probably < Turkic; a Chinese source is extremely dubious). Turk. > Mong. tümen (see TMN 2, 641, Щербак 1997, 160), whence Evk. tumen etc., see Doerfer MT 78. Weak evidence of initial voice (*d- should be expected in PT) may be due to later cultural interborrowing.
