忠実

The word "chūjitsu" carries two distinct primary nuances depending on the object it modifies. When applied to people or animals, it describes a state of unwavering loyalty, devotion, and obedience to a superior or a duty. It implies a strong emotional and moral bond, often associated with a sense of duty or honor.

When applied to objects, texts, or representations, it shifts to mean "faithful" or "accurate." In this context, it describes how closely a copy, translation, or reproduction adheres to the original source without adding, omitting, or distorting information. It is not just about being "correct" (tadashii), but about maintaining the integrity and essence of the original.

Compared to "chūsei" (loyalty), which is a noun referring to the abstract concept of loyalty itself, "chūjitsu" is an adjectival noun used to describe the quality of a person or the nature of a reproduction. While "chūsei" is often used in formal or historical contexts (e.g., loyalty to a king), "chūjitsu" is more versatile and commonly used in everyday contexts, such as describing a loyal pet or a faithful movie adaptation.
