Which term best describes someone who is friendly and warm?

The term "amiable" is the best descriptor for someone who is friendly and warm. This word conveys a sense of friendliness and pleasantness, indicating that a person is approachable and engages with others in a positively affectionate manner. Amiable people often create a comfortable atmosphere for social interactions, making them well-liked and respected in their communities.

In contrast, the other options suggest dispositions that do not align with friendliness. "Hostile" implies aggression or unfriendliness, which is the opposite of being warm and welcoming. "Indifferent" describes a lack of interest, concern, or enthusiasm, indicating a neutral or detached attitude rather than one that is friendly. Finally, "apathetic" suggests a state of indifference or lack of feeling, which also does not align with warmth or friendliness. Therefore, "amiable" is the most fitting choice to describe someone with a friendly and warm demeanor.
