A more modern etymology was advocated by Gordon M. Day in 1968, elaborating upon Charles Arnaud from 1880. Arnaud had claimed that the word came from Montagnais 
irnokué, meaning "terrible man", via the reduced form 
irokue. Day proposed a hypothetical Montagnais phrase 
irno kwédač, meaning "a man, an Iroquois", as the origin of this term. For the first element 
irno, Day cites cognates from other attested Montagnais dialects: 
irinou, 
iriniȣ, and 
ilnu; and for the second element 
kwédač, he suggests a relation to 
kouetakiou, 
kȣetat-chiȣin, and 
goéṭètjg – names used by neighboring Algonquian tribes to refer to the Iroquois, Huron, and 
Laurentian peoples.
