Scattered letters in a press (6)
I believe the answer is:
sparse
'scattered' is the definition.
(I've seen this in another clue)
'letters in a press' is the wordplay.
'letters in' indicates anagramming the letters.
'a'+'press'='apress'
'apress' with letters rearranged gives 'SPARSE'.
(Other definitions for sparse that I've seen before include "Infrequent" , "Rare" , "Thinly dotted about" , "Scarce like thinning hair" , "Thinly spread" .)
