'sleazy' is the definition.
Both the definition and answer are adjectives.
Perhaps they are linked in a way I don't understand?

'newspaper disheartened girl in particular' is the wordplay.
'newspaper' becomes 'rag' (informal term for a newspaper).
'disheartened' means to remove the middle letters (the middle or heart is removed).
'in' means one lot of letters goes inside another.
'particular' becomes 'detailed' (I've seen this before).
'girl' with its centre removed is 'gl'.
'rag'+'gl'='raggl'
'raggl' inserted inside 'detailed' is 'DRAGGLE-TAILED'.
