Fashionable people in Land's End, full of bluster (2-5)
I believe the answer is:
in-crowd
'fashionable people' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'in land's end full of bluster' is the wordplay.
'end' suggests the final letters.
'full of' indicates putting letters inside.
'bluster' becomes 'crow' (crowing is a kind of blustering**).
The last letter of 'land' is 'd'.
'in'+'d'='ind'
'ind' placed around 'crow' is 'IN-CROWD'.
Can you help me to learn more?
(Other definitions for in-crowd that I've seen before include "Cool people" , "Fashionable coterie" , "Fashionable group" , "Clique considered by others to be fashionable" , "Small group of popular people" .)
