The root presents considerable difficulties because of widespread later interlingual borrowings (see TMN 2, 125, Щербак 1997, 97-98). A specific problem is raised by initial h- in some Southern Mongolian forms (Dong. hamura-, Bao. hamera-, Mongor xamurā- 'to rest'). The aspiration here is evidently secondary, because it is absent both in Dagur and in most attested Middle Mongolian sources (but cf. MA hamisqu). It is, therefore, probable that these forms are in fact borrowed from modern Turkic dialects with secondary aspiration (cf. h- in Khalaj). This would be indeed an argument in favour of the whole *amura- group of words in Mong. to be regarded as borrowed from Turkic (although later reborrowings into modern Turkic languages were, of course, also possible). However, significant semantic and formal differences do not allow us to regard as borrowed, on the one hand, the Turkic forms going back to attested Old Uyghur (e.g. amɨr- 'to love), on the other hand, Mong. ami-n 'life, soul' and amu- 'to rest'.
