The Vietnamese word "tâm phúc" is an adjective that means "very reliable" or "trustworthy." It describes someone or something that you can depend on completely, someone who is loyal and consistent in their actions or words.
In more formal or literary contexts, "tâm phúc" can also imply a deep emotional connection or loyalty that goes beyond mere reliability. For example, you might use it to describe a confidant or someone who supports you through difficult times.
There aren't direct variants of "tâm phúc," but it is often used in phrases with other adjectives or nouns to emphasize the reliability or trustworthiness of something or someone, like "người bạn tâm phúc" (trusted friend) or "mối quan hệ tâm phúc" (trustworthy relationship).
While "tâm phúc" primarily means "very reliable," in some contexts, it can also imply a sense of emotional depth in the relationship, suggesting that the person is not only reliable but also deeply caring and supportive.
