What is the traditional Easter candle used in Western Christian churches called?

The traditional Easter candle used in Western Christian churches is called the Paschal candle.

The Paschal candle is a large candle lit during the Easter Vigil, the service held after sunset on Holy Saturday. Its lighting symbolizes the resurrection of Jesus and the victory of light over darkness. The candle is then used during the Easter season and often remains near the altar or baptismal font.

Many Paschal candles bear a cross, the Greek letters Alpha and Omega, and the current year. Some traditions also insert five grains of incense into the candle, representing the five wounds of Christ. The candle may be carried into the dark church at the beginning of the vigil.

The term comes from Pascha, the Christian name for Easter derived from the Hebrew word associated with Passover. Orthodox churches use a related Paschal candle tradition, though the ceremonies and candle styles differ between denominations.
