A hellebore for a festival girl (9,4)
I believe the answer is:
christmas rose
'a hellebore' is the definition.
(Christmas rose is an example)
'a festival girl' is the wordplay.
I cannot quite understand how this works, but
'festival' could be 'christmas' (I've seen this before) and 'christmas' is located in the answer.
'girl' could be 'ros' and 'ros' is found within the answer.
A single letter 'e' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'for' acts as a link.
Can you help me to learn more?
(Other definitions for christmas rose that I've seen before include "Variety of hellebore" , "Helleborus niger is its Latin name" , "Black hellebore" .)
