National greeting for spotless environment all around (7)
I believe the answer is:
chilean
'national' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'greeting for spotless environment all around' is the wordplay.
I cannot really see how this works, but
'greeting' could be 'hi' (hi is a kind of greeting) and 'hi' is located in the answer.
'spotless' could be 'clean' (similar in meaning) and 'clean' is found within the leftover letters.
This accounts for all the letters.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for chilean that I've seen before include "From e.g. Valparaiso" , "Santiago-born" , "from South American country" , "Spanish speaker" , "Native of, eg, Santiago" .)
