Laredo's terrible trials (7)
I believe the answer is:
ordeals
'trials' is the definition.
(I've seen this in another clue)
'laredo's terrible' is the wordplay.
'terrible' indicates anagramming the letters.
'laredos' anagrammed gives 'ORDEALS'.
(Other definitions for ordeals that I've seen before include "Tribulations" , "Testing experiences" , "Difficult experiences, hard times" , "Trying experiences" , "difficult tests" .)
