Classification
There are two definitions for Dravidian ethnicity which are generally divided between proposing that Dravidian people are an ethnic group in their own right, or Dravidian peoples are a collective group of ethnolinguistic ethnicities. The World Book encyclopedia, Volume 10 says: "Most southern Indians belong to the Dravidian ethnic group;" referring to them as one ethnic group, while the The New Encyclopaedia Britannica: Volume 8; Volume 21 refers to 'Dravidian ethnic groups', suggesting the latter definition. Hence, depending on the definition and context, both 'Dravidian people' and 'Dravidian peoples' may be used.
