Did he father the television series? (3)
I believe the answer is:
ted
'did he father the television series?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'did he father the' is the wordplay.
I cannot really see how this works, but
'he' could be 'ed' (short for Edward) and 'ed' is found in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ted that I've seen before include "- Hughes, Eng. Poet" , "Edward, in short" , "Familiar form of Edward" , "Comic TV priest by the late Dermot Morgan" , "Father ..., Dermot Morgan's TV creation" .)
