You enjoy watching this splashy dive by a duck (5)
I believe the answer is:
video
'you enjoy watching this splashy' is the definition.
The definition suggests a singular noun which matches the answer.
'dive by a duck' is the wordplay.
I cannot really understand how this works, but
an anagram of 'dive' is 'vide' which is within the answer.
'duck' could be 'o' (resembles zero - 'duck' in cricket) and 'o' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for video that I've seen before include "TV cassette" , "Recording medium" , "Transmitter of televised image" , "(Tape for) recorder of film etc" , "Recording tape for visual images" .)
