The price of thoughtfulness? (5)
I believe the answer is:
penny
This could be a double definition.
'the price' is the first definition.
The definition and answer can be both related to property as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'thoughtfulness?' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'of' is the link.
Can you help me to learn more?
(Other definitions for penny that I've seen before include "coin, decimal with 1a [NEW]" , "Copper coin" , "British coin" , "Denarius" , "p; small coin" .)
