Father remaining hoarse ultimately -- here's a lozenge! (8)
I believe the answer is:
pastille
'a lozenge' is the definition.
(I know that pastille is a type of lozenge)
'father remaining hoarse ultimately' is the wordplay.
'father' becomes 'pa' (pa can mean dad or father).
'remaining' becomes 'still' (I can't justify this - if you can you should give a lot more credence to this answer).
'ultimately' suggests the final letters.
The final letter of 'hoarse' is 'e'.
'pa'+'still'+'e'='PASTILLE'
'here's' acts as a link.
Can you help me to learn more?
(Other definitions for pastille that I've seen before include "Suck this" , "Lozenge, to soothe the throat perhaps" , "something for a sore throat" , "Lozenge, small sweet for sucking" , "Small sweet/lozenge" .)
