In "Webster's New Collegiate Dictionary", the terms "crackpot", "crackbrain", and "cracked" are synonymous, and suggest a metaphorically "broken" head. The words "crazy" and "crazed" also originally meant "broken" and derive from the same root word as "cracked". The dictionary gives no indication that "pate" and "pot" have the same root, despite their apparent similarity, and implied colloquial use of "pot" to mean "head" in the word "crackpot". However, the term "craze" is also used to refer to minute cracks in pottery glaze, again suggesting the metaphorical connection of cracked pots with questionable mental health.
