The phrase "more scaring" is not often used in English. However, the word "scaring" is derived from the verb "scare", which dates back to the 13th century. The word "scare" comes from the Old Norse word "skirra" meaning "to scare" or "frighten". Over time, it evolved into "scaren" in Middle English and eventually became "scare" as we know it today. The addition of the word "more" simply indicates an increased level of scariness.
