A monstrance is the vessel use in the Roman Catholic, Old Catholic, and Anglican Churches to display the consecrated Eucharistic Host, during Eucharistic adoration or Benediction of the Blessed Sacrament. The word monstrance comes from the Latin word monstrare, meaning "to show", and is cognate with the English word demonstrate, meaning "to show clearly". In Latin, the monstrance is known as an ostensorium (from ostendere "to show"), and in England it is called a monstre/monstral.
