Again doctors suggest in hideaways (8)
I believe the answer is:
retreats
'hideaways' is the definition.
(I know this)
'again doctors' is the wordplay.
'again' becomes 're' (prefix meaning 'again').
'doctors' becomes 'treats' (I've seen this before).
're'+'treats'='RETREATS'
'suggest in' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for retreats that I've seen before include "Of army, falls back before enemy attack" , "Backs away" , "Recedes" , "Refuges" , "Places that afford peace and quiet" .)
