✅ Loyal is the best word to describe steady and devoted allegiance to a person or cause (a loyal friend; a loyal follower).
✅ Faithful is the best word to describe steadfast loyalty to someone or something that you’re bound to because of a pledge, duty, or obligation (a faithful employee; She was a faithful and supportive friend).
✅ The meaning of these words overlap substantially. However, loyal often emphasizes unswerving, dedicated allegiance, whereas faithful emphasizes a longstanding and especially devoted loyalty, often one that involves feelings of care or friendship.
✅ Loyal and faithful can also be used in the context of a romantic relationship, where they both describe a partner who wouldn’t betray the presumed obligations of the relationship (a faithful partner; I’ve always been loyal to him).
