 " Cougar " may be borrowed from the archaic Portuguese <unk> ; the term was originally derived from the <unk> language <unk> <unk> , meaning " similar to deer ( in hair color ) " . A current form in Brazil is <unk> . It may also be borrowed from the <unk> language term <unk> ara or <unk> ara . Less common Portuguese terms are onça @-@ <unk> ( brown onça , in distinction of the black @-@ spotted [ yellow ] one , onça @-@ <unk> , the jaguar ) or <unk> @-@ <unk> ( lit. chestnut lion ) , or unusually non @-@ native puma or <unk> @-@ da @-@ <unk> , more common names for the animal when native to a region other than South America ( especially for those who do not know that <unk> are found elsewhere but with a different name ) . People in rural regions often refer to both the cougar and the jaguar as simply <unk> ( she @-@ cat ) , and outside of the Amazon , both are colloquially referred to as simply onça by many people ( that is also a name for the leopard in Angola ) .
