The word kin 'hate, venom, spite' is quite unusual and took my attention for its meaning 'venom'. Is it an Anatolian-Turkish/Azeri only word or is it common in other Turkic languages? Does anyone know of any commentary on its etymology?
I totally agree with fdb. Although I cannot say if it is used in Central Asian Turkic Languages( Turkmen, Uzbek and Uighur), for certain I can say that (not sure about today but) it existed in Azerbaijani. Look at the example from Fuzuli: "Gam değil ehl-i garaz eylerse benden men’-i hayr / Gam değil ehl-i hased bağlarsa ben miskîne kin"
edit: A quick search revelead that it is used in Uzbek, Bashkurt, Tatar (no Crimean), Turkmen and Azerbaijani. http://tdk.gov.tr/index.php?option=com_lehceler&arama=lehceler&guid=TDK.LHC.58cd91f5221869.95997362
