The word ghast may either be a recent back-formation, arising from either the word "", which came from Anglo-Saxon "gāstlīc" = "like a ghost"; or the word "", from the Middle English "gāstēn" to frighten. Or alternatively Lovecraft may have derived it directly from the Anglo-Saxon form of the word "ghost": "gāst".
