Jane Austen wrote that "there is no charm ____ to tenderness of heart” (5)
I believe the answer is:
equal
This could be a double definition.
'jane austen wrote that there is no charm' is the first definition.
The definition suggests a singular noun which matches the answer.
'tenderness of heart' is the second definition.
The answer and definition can be both related to thinking as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'to' is the link.
Can you help me to learn more?
(Other definitions for equal that I've seen before include "Peer; rival" , "Peer; evenly balanced" , "Keep pace with - peer" , "Match; peer" , "The same in quantity, status etc" .)
