Ruby red sealant? (3)
I believe the answer is:
wax
This could be a double definition.
'ruby' is the first definition.
The definition and answer can be both substances as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'red sealant?' is the second definition.
The definition and answer can be both substances as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for wax that I've seen before include "Substance in candles" , "Cere - grow larger" , "Grow large" , "Increase (as moon's phase)" , "Yellow stuff secreted in ear" .)
