A nice place to be stranded! (5)
I believe the answer is:
beach
'a nice place to be stranded' is the definition.
I can't judge whether this definition defines the answer.
'a nice place to be' is the wordplay.
'nice place' becomes 'ch' (I can't explain this - if you can you should give a lot more credence to this answer).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'a'+'ch'='ach'
'ach' after 'be' is 'BEACH'.
Can you help me to learn more?
(Other definitions for beach that I've seen before include "Shore between high and low water mark" , "Sandy area by water" , "Coast" , "Sands" , "Accessible shoreline" .)
