Tried to, when one looked for (6)
I believe the answer is:
sought
This clue could be a double definition.
'tried' is the first definition.
('seek' can be a synonym of 'try')
'one looked for' is the second definition.
(I've seen this before)
'to when' acts as a link.
This may not be correct. Some or all of it may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for sought that I've seen before include "Looked for" , "Searched for - investigated - desired" , "Tried to find" , "Wanted" , "Attempted to find" .)
