Stretched and was in pain again (7)
I believe the answer is:
reached
'stretched and was in pain again' is the definition.
I can't tell whether this definition defines the answer.
'stretched and was in pain' is the wordplay.
'stretched' becomes 're' (I can't explain this - if you can you should believe this answer much more).
'and' is a charade indicator (letters next to each other).
'was in pain' becomes 'ached' (I've seen this in another clue).
're'+'ached'='REACHED'
Can you help me to learn more?
(Other definitions for reached that I've seen before include "Cad here (anag.)" , "Came to (a place)" , "Attained" , "Stretched or arrived" .)
