The name Merig comes from the Mota language. It comes from a Proto-Torres-Banks form *m÷era riãi "the small boy" via haplology to *m÷eriãi. It contrasts with Merelava, from *m÷era-i laòa "the big boy". The native term in Mwerlap is NÃÂwërig , from the same etymon.
The first recorded sighting of Merig Island by Europeans was by the Spanish expedition of Pedro Fernández de Quirós on 25 April 1606. It was then named ÃÂle Sainte Claire.
As of 2009, Merig was only inhabited by three households, consisting of 12 individuals. Merig was not listed in Vanuatu's 2020 census.
The inhabitants of Merig speak Mwerlap, the language of the neighbouring island Merelava.
