'cosy' is the definition.
Both the answer and definition are adjectives. Maybe you can see an association between them that I don't see?

'western leader with weapons' is the wordplay.
'leader' says to take the initial letters.
'with weapons' becomes 'armed' (I've seen this in another clue).
The first letter of 'western' is 'w'.
'w'+'armed'='WARMED'
