What is the meaning of sacrament according to the Council of Trent?

The standard catechetical definition was: An Outward Sign, Instituted by God, to Give Grace. Traditionally there are seven: Baptism, Penance (Confession), Holy Eucharist (Communion) Confirmation, Holy Orders (Ordination) Exteme Unction (Last rites of the Dying or seriously Ill) and Matrimony. alternate titles listed in parentheses. it should be noted there is a difference between sacraments- defined above, and Sacrmentals. Sacramentals, as a plural noun is a catch-all term for religious articles and includes such things as Palms used on Palm Sunday, Crucifixes and Crosses, Statuary, and such customary rituals as the Sign of The Cross and the Rosary these are NOT strictly speaking sacraments but are sacramentals ( Noun Plural, not adjective). Holy orders and Confirmation can only be bestowed by a Bishop or above. something like re4cieving communion from the Pope is not a special sacrament merely an applicaiton or extension of the Eucharist or Communion. There is a popular tendency when the adjective Blessed is added to refer to this Sacrament as the Blessed Sacrament- it always means communion. Benediction is NOT considered a sacrament though it has a complicated ritual and all sorts of religious articles such as incense burners, the Monstrance, etc. That about covers it.
