Here's why:
* Meaning: "Touchy" describes someone who is easily offended or upset. It's more about a quality or characteristic than something that can be measured in degrees.
* Informal Use: While you could technically say someone is "more touchy" or "the most touchy," it's not common usage and sounds awkward.
Alternatives:
If you want to express a greater degree of sensitivity, you can use synonyms or phrases like:
* More sensitive
* Highly sensitive
* Extremely sensitive
* Overly sensitive
* Thin-skinned
* Easily offended
These alternatives provide a more nuanced and natural way to express the idea of someone being more touchy than another.
