Meaning
The kanji 妄 (MŌ, BŌ; みだり) primarily conveys meanings such as delusion, folly, groundless, wild, arbitrary, and reckless. It strongly communicates a sense of irrationality, baselessness, or acting without proper consideration or permission. This kanji frequently appears in advanced Japanese contexts, particularly when discussing mental states, unfounded claims, or inappropriate actions.
Its origin offers a fascinating insight. It is composed of two simpler elements: 亡 (ぼう), meaning 'to perish,' 'to lose,' or 'to disappear,' and 女 (おんな), meaning 'woman.' While the combination of 'lost' and 'woman' might seem perplexing at first glance, the 女 component here is often interpreted as a phonetic element or sometimes linked to a broader sense of disorder or confusion. For learning purposes, a simpler and more common etymology focuses on 亡 conveying a 'lost' state. This includes lost reason or judgment, directly leading to the idea of delusion or acting wildly. Visually, the shape of 亡 itself resembles a person with something missing or falling off. This can reinforce the concept of something being 'lost' or 'misplaced,' thus suggesting 'groundless' or 'delusional' thoughts.
This kanji has 6 strokes and is considered an N1 level kanji in the Japanese Language Proficiency Test (JLPT) system. It is not part of the standard Kyōiku Kanji list taught in Japanese elementary schools.
Readings
On'yomi (音読み) — Chinese-derived readings
The On'yomi readings of 妄 are derived from Chinese pronunciations and are primarily used when 妄 forms part of a compound word. The two main On'yomi are モウ (MŌ) and ボウ (BŌ).
- モウ (MŌ): This is the more common and widely used On'yomi for 妄 in modern Japanese. It appears in most common compound words, typically associated with delusion, wildness, and baselessness. For example:
妄想 (mōsō) — delusion, wild fancy, hallucination
妄言 (mōgen) — wild talk, baseless remark, irresponsible statement
妄信 (mōshin) — blind faith, credulity
- ボウ (BŌ): While ボウ is also listed as an On'yomi, it is much less frequently encountered in modern common vocabulary compared to モウ. Historically, some words might have used ボウ, but モウ has largely become dominant. It may occasionally appear in specific, older texts or proper nouns.
Kun'yomi (訓読み) — Native Japanese readings
The Kun'yomi reading of 妄 is tied to native Japanese words and expresses the kanji's meaning directly in isolation or with okurigana.
- みだり (midari): This reading is almost exclusively found in the adverbial form 妄りに (midarini). It signifies acting 'recklessly,' 'arbitrarily,' 'without permission,' 'improperly,' or 'unnecessarily.' It denotes actions taken without due care, authority, or reason, such as 妄りに物を捨てる (midarini mono o suteru - to carelessly discard things) or 妄りに他人の私物に触る (midarini tanin no shibutsu ni sawaru - to arbitrarily touch someone else's personal belongings).
妄りな (midarina) — reckless, arbitrary (adjectival form), e.g., 妄りな行動 (midarina kōdō - reckless action)
妄り言 (midarigoto) — (less common) wild talk, gossip

Memory Tip
To remember 妄, think of its components: 亡 (bō - to perish, to lose) and 女 (onna - woman). Imagine a situation where someone's mind has "perished" or become "lost" (亡), leading them to act in a delusional or reckless (妄) manner. Alternatively, you could visualize a "lost woman" (亡 + 女) who is prone to groundless ideas or wild talk, perhaps speaking "recklessly" (妄りに). The key is to connect the "lost" aspect of 亡 with the irrationality or baselessness that 妄 represents. When reason is lost, delusion takes hold.
