Relating to ethnology; concerning the study of different ethnic groups and their cultures, origins, and characteristics.
From ethnology + -ic (Greek suffix meaning 'of or pertaining to'). This rare form competes with the more common 'ethnological,' showing how English tolerates multiple adjectival forms.
Both 'ethnologic' and 'ethnological' mean essentially the same thing, but 'ethnological' dominated—this happens throughout English where one variant simply wins out through usage, like how 'internet' won over 'internets.'
