the.com/last rite

means A final set of religious rites given to someone who is dying, meant to prepare and reconcile them before death.

from From 'rite,' rooted in Latin 'ritus' meaning a religious ceremony or custom. 'Last' simply marks finality — the rite performed at the end rather than a special separate word. In Catholic tradition this cluster of rites (confession, anointing, final communion) came to be called 'last rites' in everyday English, though the formal liturgical term is 'anointing of the sick' — 'last rites' is the folk-shorthand that stuck because it says exactly what it is.
