The term "Aboriginal person" can refer to different groups of people depending on the context. Here are some possible meanings:

• In Canada, "Aboriginal identity" refers to whether a person reported identifying with the Aboriginal peoples of Canada, including First Nations (North American Indian), Métis or Inuit, and/or those who reported Registered or Treaty Indian status, that is registered under the Indian Act of Canada, and/or those who reported membership in a First Nation or Indian band.
• In Australia, "Aboriginal Australians" are the various Indigenous peoples of the Australian mainland and many of its islands, but excluding the ethnically distinct people of the Torres Strait Islands. The term "Indigenous Australians" is applied to Aboriginal Australians and Torres Strait Islanders collectively. The term "Aboriginal person" is defined by the Commonwealth Parliament as "a person who is a member of the Aboriginal race of Australia".
• The term "Aboriginal" is generally perceived as insensitive in Australia because it has racist connotations from Australia’s colonial past, and lumps people with diverse backgrounds into a single group. Instead, it is recommended to say "Aboriginal person", "Aboriginal", or "Torres Strait Islander". If possible, using the person’s clan or tribe name is even better. When talking about both Aboriginal and Torres Strait Islander people, it’s best to say either "Indigenous Australians" or "Indigenous people".
• In general, the term "Aboriginal" can also be used as an adjective to describe something that is of or relating to the people who have been in a region from the earliest time, or of or relating to aborigines. For example, "aboriginal languages" or "aboriginal tribes/customs/art".

It is important to note that the definition of "Aboriginal person" can vary depending on the context and the preferences of the individuals, families, or communities involved.
