Decide to do this a second time (7)
I believe the answer is:
resolve
This could be a double definition.
'decide' is the first definition.
(I know that resolve is a more specific form of decide)
'do this a second time' is the second definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'to' acts as a link.
Can you help me to learn more?
(Other definitions for resolve that I've seen before include "Make a firm decision" , "12 [STIFF UPPER LIP]" , "Find the solution (to)" , "Decide; firm determination" , "Sort out (a problem)" .)
