What do affectivity and emotions mean to you? Where is the difference?

If we refer to colloquial language, affectivity and emotionality could almost be considered synonyms. However, etymology and scientific research have contributed to our understanding of what emotion, affection, and feeling truly are.
In current literature, is considered a broad concept that encompasses the complex interplay of affective phenomena. Within these affective phenomena, we find emotions, feelings, emotional states, emotional disorders, and even personality traits.
In this sense, we could say that is a broader concept if we adopt this definition. However, there is also a connotation that might be perceived as something "lighter," while is seen as more intense. This is because emotion is a neurophysiological response of the body to stimuli and thoughts. We know an emotion is present when this response occurs, involving hormonal secretions, neurotransmitters, etc.
So, if the question is about versus , I believe that, in general, most people would consider them synonyms. From there, we could analyze their differences more precisely, depending on the approach we want to take—does that make sense?
