Distress George in Riga disaster the day before? (8)
I believe the answer is:
aggrieve
'distress' is the definition.
(I've seen this before)
'george in riga disaster the day before?' is the wordplay.
'george' becomes 'g'.
'in' indicates putting letters inside.
'disaster' is an anagram indicator.
'the day before?' becomes 'eve' (eve is the night before something).
'riga' is an anagram of 'agri'.
'g' going into 'agri' is 'aggri'.
'aggri'+'eve'='AGGRIEVE'
(Other definitions for aggrieve that I've seen before include "Make resentful" , "Do an injustice to" , "Trouble" , "Cause pain to; distress" , "Hurt" .)
