Interviewed for observation? (4)
I believe the answer is:
seen
'interviewed for observation?' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Maybe there's an association between them I don't understand?
This is all the 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" .)
