Dim seabird flying around wedding participant (10)
I believe the answer is:
bridesmaid
'wedding participant' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
'dim seabird flying' is the wordplay.
'flying' indicates an anagram (letters fly around into new positions).
'dim'+'seabird'='dimseabird'
'dimseabird' anagrammed gives 'BRIDESMAID'.
'around' acts as a link.
Can you help me to learn more?
(Other definitions for bridesmaid that I've seen before include "one's holding up train perhaps" , "match participant" , "Attendant at wedding" .)
