The taboo on the dead includes the taboo against touching of the dead and those surrounding them; the taboo against mourners of the dead; and the taboo against anything associated with the dead.
Among the Shuswaps of British Columbia widows and widowers in mourning are secluded and forbidden to touch their own head or body; the cups and cooking vessels which they use may be used by no one else. [...] No hunter would come near such mourners, for their presence is unlucky. If their shadow were to fall on anyone, he would be taken ill at once. They employ thorn-bushes for bed and pillow, in order to keep away the ghost of the deceased; and thorn bushes are also laid all around their beds.
Among the Agutainos, who inhabit Palawan, the Philippines, a widow may not leave her hut for seven or eight days after the death; and even then she may only go out at an hour when is not likely to meet anybody, for whoever looks upon her dies a sudden death. To prevent this fatal catastrophe, the widow knocks with a wooden peg on the trees as she goes along, thus warning people of her dangerous proximity; and the very trees on which she knocks soon die."

Among the Guaycurus of Paraguay, when a death had taken place, the chief used to change the name of every member of the tribe; and from that moment everybody remembered his new name just as if he had borne it all his life.
After a Yolngu man named Bitjingu died, the word bithiwul "no; nothing" was avoided. In its place, a synonym or a loanword from another language would be used for a certain period, after which the original word could be used again; but in some cases the replacement word would continue to be used.
