The term 'altar plate' refers to a type of religious object used in many different religions. The paten, which is a five-letter word, is a shallow plate used to hold the bread during the Eucharist. The ara, a three-letter word, is a type of altar found in Christian churches. Finally, the APSE, a four-letter word, is a semicircular recess in the wall of a church, typically at the end of the choir or chancel. Altar plates are often placed on the ara and in the APSE.
