Consumed by fury, nanny's heading for a row (5)
I believe the answer is:
range
'a row' is the definition.
(I've seen this before)
'consumed by fury nanny's heading' is the wordplay.
'consumed by' indicates putting letters inside (I've seen this in other clues).
'fury' becomes 'rage' (synonyms).
'heading' says to take the initial letters (head could mean the top letter).
The first letter of 'nannys' is 'n'.
'rage' placed around 'n' is 'RANGE'.
'for' acts as a link.
(Other definitions for range that I've seen before include "Number of items in a series" , "testing ground" , "Area for shooting practice" , "Take sides" , "Scope (for target practice?)" .)
