An esbat /ˈɛsbæt/ is a coven meeting of other than one the Sabbats within Wicca and other Wiccan-influenced forms of contemporary Paganism. Janet and Stewart Farrar describe esbats as an opportunity for a “love feast, healing work, psychic training and all.”
The term esbat is derived from Old French s’esbattre (Modern French ébat), meaning to frolic and amuse oneself, diversion. It was a borrowing by 20th century anthropologist Margaret Murray’s use of French witch trial sources on supposed Witches’ Sabbaths in her attempts to “reconstruct” a Witch Cult in Western Europe.
An esbat is commonly understood to be a ritual observance on the night of a full moon. However, the late high priestess Doreen Valiente distinguished between “full moon Esbat[s]” and other esbatic occasions.
The term esbat in this sense was described by Margaret Murray.
The Esbat differed from the Sabbat by being primarily for business. … very often the Esbat was for sheer enjoyment only—Murray, 1921
