allergic

The term describes a physiological reaction where the immune system overreacts to a normally harmless substance. In medical contexts, it is a neutral, descriptive term used to identify specific triggers and sensitivities.

When used figuratively, the word shifts toward a tone of strong aversion or irrational dislike. This usage is typically informal or hyperbolic, framing a psychological preference as if it were an involuntary physical repulsion, such as being "allergic to hard work" or "allergic to criticism."
