One fabulous female of a thousand I dream about, maybe (7)
I believe the answer is:
mermaid
'one fabulous female' is the definition.
(I've seen this before)
'a thousand i dream about maybe' is the wordplay.
I cannot really understand how this works, but
'a' is within the answer.
'thousand' could be 'm' (Roman numeral for a thousand) and 'm' is found in the answer.
'i' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for mermaid that I've seen before include "London theatre?" , "Woman with tail of fish" , "Mythical sea dweller" , "Imaginary woman of the sea" , "'Half woman, half fish (7)'" .)
