Sweet cryptic clue accepted by Daily Telegraph initially (6)
I believe the answer is:
dulcet
'sweet' is the definition.
(I know that sweet can be written as dulcet)
'cryptic clue accepted by daily telegraph initially' is the wordplay.
'cryptic' indicates an anagram (a cryptic or obscure order of the letters).
'accepted by' indicates putting letters inside (inserted letters are accepted).
'initially' says to take the initial letters.
The first letters of 'daily telegraph' is 'dt'.
'clue' with letters rearranged gives 'ulce'.
'ulce' inserted within 'dt' is 'DULCET'.
(Other definitions for dulcet that I've seen before include "Sweet on the ear" , "Agreeable and soothing to the ear" , "Sweet - melodious" , "Sweet, gentle (tones)" , "Mellifluous, pleasant to the ear" .)
