Gave all the information to while one dealt with the forms (6,2)
I believe the answer is:
filled in
'gave' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for filled in that I've seen before include "well-informed" , "Acted as substitute" , "informed?" .)
