The ‘general fact’ copula in Yolmo and the influence of Tamang

This paper examines the similarity of the Yolmo ‘general fact’ evidential and the ‘generic fact’ evidential in the Tamang dialect spoken in the valley of the Indrawati Khola. Yolmo òŋge is unlike any evidential attested in other Tibetic languages, but shares features with ¹kha-pa in the local dialect of Tamang. Semantically, they both are used for situations that are generally known facts. Structurally, both are copulas with evidential functions that are formed using the lexical verb ‘come’. We argue that language contact between Tamang speakers of the Indrawati Khola area and Yolmo speakers in the Melamchi Valley led to the Yolmo language calquing the Tamang form. We illustrate these copulas and their relationship because grammaticalisation of copulas from a lexical verb ‘come’ is cross-linguistically uncommon.
