In distress, dour men lamented (7)
I believe the answer is:
mourned
'lamented' is the definition.
(I've seen this in another clue)
'in distress dour men' is the wordplay.
'in distress' indicates anagramming the letters.
'dour'+'men'='dourmen'
'dourmen' with letters rearranged gives 'MOURNED'.
(Other definitions for mourned that I've seen before include "No demur about the late departed" , "Grieved, sorrowed" , "Grieved for, lamented" .)
