'single-tribe' originates from the combination of 'single,' meaning 'one' or 'individual,' and 'tribe,' which comes from Latin 'tribus,' referring to a group or community.

'tribe' changed from the Latin word 'tribus' and eventually became the modern English word 'tribe.'

Initially, 'tribe' referred to a division of the Roman people, but over time it evolved into its current meaning of a group of people with a common culture or identity.
