Fetching sliced cheese at last (4)
I believe the answer is:
cute
'fetching' is the definition.
(I've seen this in another clue)
'sliced cheese at last' is the wordplay.
'sliced' becomes 'cut' (similar in meaning).
'at last' says to take the final letters.
The final letter of 'cheese' is 'e'.
'cut'+'e'='CUTE'
(Other definitions for cute that I've seen before include "Attractive or quaint, as in America" , "Small, delightful" , "Attractive and quaint (4" , "Quaintly attractive" , "Sweet, attractive" .)
