👉 In a philosophical context, "submaniacal" is an adjective used to describe someone who appears to be possessed by a delusional or irrational thought and behavior. The term implies that this person may have a severe mental disorder that causes them to act in a strange, unpredictable, or dangerous manner. It's important to note that the term is not widely recognized in everyday speech or usage, so it might not be used as commonly as other terms like "mad" or "madman."
