"careful"是英語中表示謹慎态度的形容詞，其核心含義包含三個維度：
細緻周全（牛津詞典）
指通過系統性的觀察或行動避免錯誤，如："The scientist was careful to record all experimental variables." 該用法常見于學術研究和技術操作場景。
風險規避（劍橋詞典）
強調對潛在危險的預防意識，例如交通安全提示："Be careful when crossing icy roads." 醫療領域也常用此義項指導用藥規範。
資源保護（韋氏詞典）
包含對物品價值的維護意識，如古董保養指南中出現的："careful handling of porcelain artifacts"。該用法在文化遺産保護領域具有特殊意義。
詞源可追溯至古英語"caru"（憂慮）與"full"（充滿）的組合，現代英語中已發展為中性詞彙。語法特征包含可接介詞"with/about"的結構："careful with confidential documents"，以及接不定式結構："careful not to disclose secrets"。
近義詞"cautious"側重潛在風險評估，"meticulous"強調細節處理；反義詞"reckless"特指危險場景中的魯莽行為。在商務信函中，常用"Please be advised that..."替代直接使用該詞以保持專業語氣。
