What 厴 means
An animal's hard cover, not a feeling.
For the crab underside sense, the earliest dictionary trail I could verify is 《廣韻》 and 《類篇》; 《說文》 does not record 厴. As of 2026, that points to a gradual specialist term, not an invented sign with a known creator.
By 1712, Japanese reference material used 厴 for a gastropod shell lid, read へた. The simplified form is 厣.
Specialized and anatomical: it names a cover, not an emotion or reaction.
Sent alone, it reads like an unexplained dictionary term.
