Name of woman taking part in declaration (5)
I believe the answer is:
clara
'name of woman' is the definition.
(I know that Clara is a female given name)
'part in declaration' is the wordplay.
'part in' indicates the answer is hidden within the clue.
'CLARA' is hidden within 'declaration'.
'taking' is the link.
(Other definitions for clara that I've seen before include "Home town of the Taoiseach" , "-- Bow, silent film actress" , "- - Bow, silent film star" , "Woman" , "- Bow, US actress, the 'It Girl'" .)
