Nice place that means nothing to a little sister (5)
I believe the answer is:
oasis
'nice place that' is the definition.
I can't judge whether this defines the answer.
'nothing to a little sister' is the wordplay.
'nothing' becomes 'O' (looks like zero - 0).
'to a' becomes 'an'.
'little' means to remove the last letter (the word is not quite complete).
'sister' becomes 'sis' (synonyms).
'an' with its last letter taken off is 'a'.
'o'+'a'+'sis'='OASIS'
'means' is the link.
Can you help me to learn more?
(Other definitions for oasis that I've seen before include "quiet spot" , "Green area in desert" , "Fertile part of desert" , "A place of safety or sanctuary" , "Fertile area in desert" .)
