Ring found with a sibling in desert's fertile spot (5)
I believe the answer is:
oasis
'fertile spot' is the definition.
(I've seen this in another clue)
'ring found with a sibling' is the wordplay.
'ring' becomes 'O' (letter resembling a ring).
'found with' means one lot of letters go next to another.
'sibling' becomes 'sis' (short for sister).
'o'+'a'+'sis'='OASIS'
'in desert's' acts as a 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 oasis that I've seen before include "quiet spot" , "Fertile area in desert" , "Area of calm amid hectic surroundings" , "place of relief" , "Green area in desert" .)
