Interviewed for observation? (4)
I believe the answer is:
seen
'interviewed for observation?' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Perhaps you can see an association between them that I can't see?
This is the entire clue.
Can you help me to learn more?
(Other definitions for seen that I've seen before include "Sighted" , "Noticed" , "Espied" , "Observed or percieved" , "Witnessed" .)
