also: ほい
noun
real intention; true motive; true will
Refers to what someone genuinely wants or intends, often contrasted with outward words or actions. Common in expressions like 本意ではない (not one's real intention).
彼の言葉は本意ではないと思う。
I don't think his words reflect his real intention.
本意を隠して愛想笑いをする。
He hides his true feelings and forces a smile.
noun
original intention; original purpose; original hope
Used for the initial aim or purpose behind an action, plan, or creation. Often appears in contexts where the original intent is contrasted with the current situation or outcome.
この制度の本意は弱者を守ることだ。
The original purpose of this system is to protect the weak.
彼の本意は別のところにあった。
His original intention lay elsewhere.
真意 also means 'true intention', but it often implies a hidden or deeper meaning behind words or actions, while 本意 focuses more on one's genuine will or original purpose.
本心 refers to one's true feelings or heart, often used in personal, emotional contexts. 本意 is broader and can refer to intentions, motives, or original aims in both personal and formal situations.
Compound of 本 (ほん, 'true, original') and 意 (い, 'mind, intention'). The reading ほい is a historical contraction, now rare.
