Grubby residence (6)
I believe the answer is:
cocoon
This might be a double definition.
'grubby' is the first definition.
The definition and answer can be both animals as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'residence' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
Can you help me to learn more?
(Other definitions for cocoon that I've seen before include "Protective case for insect" , "Protection for pupa" , "Protect" , "secure environment" , "Silky sheath around a chrysalis" .)
