Kind of spray (5)
I believe the answer is:
'kind of spray' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nasal that I've seen before include "Relating to one's hooter" , "of a prominent feature" , "Sounding affected by cold" , "like the sound from an organ" , "Describing some hooter" .)
