loyalty
[U] Uncountable
This term describes a psychological bond that transcends simple agreement or preference. It implies a steadfast commitment that remains intact even when the other party makes mistakes or when circumstances become difficult. It is the emotional glue that binds a soldier to a commander or a fan to a sports team. In a commercial sense, it describes the habitual preference for a specific brand. While interpersonal loyalty is viewed as a noble virtue, brand loyalty is often seen as a result of clever marketing or convenience, though it still mirrors the same underlying pattern of refusal to switch to an alternative.
The quality of being loyal is an abstract trait that cannot be counted.
