More unhappy about the way you swagger and talk boastfully (7)
I believe the answer is:
bluster
'you swagger and talk boastfully' is the definition.
I can't tell whether this definition defines the answer.
'more unhappy about the way' is the wordplay.
'more unhappy' becomes 'bluer' (I've seen this in another clue).
'about' means one lot of letters goes inside another.
'the way' becomes 'st' (abbreviation for street).
'bluer' enclosing 'st' is 'BLUSTER'.
Can you help me to learn more?
(Other definitions for bluster that I've seen before include "Boastful and bullying talk" , "Sound off" , "Swaggering language" , "Braggadocio" , "Empty boasting" .)
