Slender new missile (6)

Ross

I believe the answer is:

narrow

'slender' is the definition.
(similar in meaning)

'new missile' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'missile' becomes 'arrow' (arrow is a kind of missile).
'n'+'arrow'='NARROW'

(Other definitions for narrow that I've seen before include "Small-minded" , "Restrict" , "Thin; taper" , "Bigoted opinion" , "Keen" .)

I've seen this clue in The Sun.
