Fire outfit with old German first (3-2-3-2)
I believe the answer is:
get-up-and-go
'fire' is the definition.
(thesaurus)
'outfit with old german first' is the wordplay.
'outfit' becomes 'getup' (synonyms).
'with' becomes 'and'.
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'german' becomes 'g' (abbreviation).
'first' says to put letters next to each other.
'o' put after 'g' is 'go'.
'getup'+'and'+'go'='GET-UP-AND-GO'
(Other definitions for get-up-and-go that I've seen before include "'pizazz'" , "Vim" .)
