The kanji 妄 primarily conveys the idea of something that is みだれ（乱れ） or むやみに（無闇に）—meaning "reckless," "groundless," "absurd," "delusional," or "false." It implies a lack of basis in reality, a lack of rationality, or a deviation from truth. The character suggests thoughts, ideas, or actions that are unfounded, inappropriate, or out of control.

⚫︎ 妄想 Translation: Delusion; delusionary thought. ⚫︎ 妄言 Translation: False statement; lie. ⚫︎ 妄想狂 Translation: Paranoiac; someone suffering from delusional disorder.

The kanji 妄 is a 形声文字 (keisei moji), a phono-semantic compound. ⚫︎ The top part of the character is a 亡 (bou, meaning death or loss), which acts as the phonetic component, suggesting the sound of the character. ⚫︎ The bottom part is 女 (onna, meaning woman). ⚫︎ The combination originally depicted something related to being confused or misguided, often associated with reckless or unfounded thoughts, and later evolved to the meaning it has today, still carrying the connotation of falseness or delusion. The 女 (onna) component may have originally hinted at the idea of being misled or the susceptibility to illusion, or possibly alluded to the perception that women could be easily swayed by irrational thoughts in the past. It's difficult to ascertain with certainty, and this interpretation is a general explanation.
