Huge woman developing in stages (8)
I believe the answer is:
giantess
'huge woman' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'developing in stages' is the wordplay.
'developing' is an anagram indicator (letters developed into a new form).
'in'+'stages'='instages'
'instages' anagrammed gives 'GIANTESS'.
Can you help me to learn more?
(Other definitions for giantess that I've seen before include "Big woman" , "Very large female" .)
