sensitivity
The word is primarily used as an uncountable noun, meaning you generally do not say "sensitivities" unless referring to different types of reactions or specific emotional triggers. In a medical or physical context, it describes how the body reacts to external stimuli. In a social context, it refers to kindness and empathy toward others' emotions. When talking about technology, it is used as a technical term to describe how precisely a machine can detect a signal.
