Men with lowered energy in Eastern lands recall trouble (7)
I believe the answer is:
amnesia
'recall trouble' is the definition.
(I've seen this before)
'men with lowered energy in eastern lands' is the wordplay.
I cannot quite see how this works, but
an anagram of 'men' is 'mne' which is within the answer.
'eastern lands' could be 'asia' (I've seen this in other clues) and 'asia' is present in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for amnesia that I've seen before include "Partial or total loss of memory" , "Inability to remember" , "Seaman I find suffering from memory loss" , "Complaint" , "Inability to recall" .)
