 Both groups have been designated as "Gabrieleño".Although their language idioms were distinguishable, they did not diverge greatly, and it is possible there were as many as half a dozen dialects rather than the two which the existence of the missions has lent the appearance of being standard.The demarcation of the Fernandeño and the Gabrieleño territories is mostly conjectural, and there is no known point in which the two groups differed markedly in customs.
