British journeys frenetic, needing introduction of one female attendant (10)
I believe the answer is:
bridesmaid
'introduction of one female attendant' is the definition.
'bridesmaid' can be an answer for 'attendant' (bridesmaid is a kind of attendant). I'm not certain of the 'introduction of one female' bit.
'british journeys frenetic' is the wordplay.
'british' becomes 'b' (abbreviation e.g. in BBC).
'journeys' becomes 'rides' (riding is a kind of journeying).
'frenetic' becomes 'maid' (I am not sure about this - if you are sure you should believe this answer much more).
'b'+'rides'+'maid'='BRIDESMAID'
'needing' 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" , "Attendant at wedding" , "match participant" .)
