任意

• 拼音: rèn yì
• 汉字拆解: 任 = 亻+ 壬 (person + bearing = take charge/allow); 意 = 音 + 心 (sound over heart = intention/will)

含义

Arbitrarily; at will; without restriction. Acting or choosing freely without constraint or fixed rules.

Used to indicate freedom of action or choice, often in academic, legal, or mathematical contexts. In formal writing, 任意 can mean 'any given' (e.g., 任意一个 = any given one). In casual usage it can carry a slightly negative nuance of recklessness or disregard for others.
