Dream I’m dancing for legendary woman (7)
I believe the answer is:
mermaid
'legendary woman' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'dream i'm dancing' is the wordplay.
'dancing' indicates an anagram.
'dream'+'im'='dreamim'
'dreamim' anagrammed gives 'MERMAID'.
'for' is the link.
Can you help me to learn more?
(Other definitions for mermaid that I've seen before include "Imaginary woman of the sea" , "Woman with tail of fish" , "Mythical sea creature" , "Mythical sea dweller" , "London theatre?" .)
