no example

This is a definition contained in Leo:

his face sunken with disappointment -> er war sichtlich enttäuscht

and it should be changed. "Face sunken with" is just a way to say "visibly" using poetic license. "Sichtlich" has nothing do do with faces being sunken, on the face of it.

And not only that, the English grammar is bad - "his face sunk with" or "his face was sunken with", but not "his face sunken with".

So, it should be:

er war sichtlich enttäuscht -> he was visibly disappointed
