Deanna might be like Nazca person (6)
I believe the answer is:
andean
'nazca person' is the definition.
I can't judge whether this defines the answer.
'deanna might be' is the wordplay.
'might be' is an anagram indicator.
'deanna' anagrammed gives 'ANDEAN'.
'like' acts as a link.
Can you help me to learn more?
(Other definitions for andean that I've seen before include "Relating to a South American chain" , "Peak District" , "one highly placed in South America" , "within range?" , "Relating to South American mountains" .)
