Hardens eccentrics (5)
I believe the answer is:
cases
This might be a double definition.
'hardens' is the first definition.
Although both the answer and definition are verbs in their -s form, I can't see how one could define the other.
'eccentrics' is the second definition.
The definition and answer can be both people as well as being plural nouns.
Maybe you can see an association between them that I don't see?
Can you help me to learn more?
(Other definitions for cases that I've seen before include "Legal or medical records" , "Lawsuits or travelling containers" , "Lawsuits or pieces of luggage" , "Law-suits or boxes" , "Proceedings in a court of law" .)
