Corrupt announcement when Teletubby appears? (6)
I believe the answer is:
poison
'corrupt' is the definition.
(poisoning is a kind of corrupting)
'announcement when teletubby appears?' is the wordplay.
I cannot quite see how this works, but
'when' could be 'on' (I've seen this in other clues) and 'on' is found in the answer.
'teletubby' could be 'po' (character in the children's TV show Teletubbies) and 'po' is found within the answer.
'appears?' could be 'is' (appearing is a kind of being) and 'is' is present in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for poison that I've seen before include "[ADDER] 's defence" , "Substance that damages tissues or causes death" , "Deadly substance" , "Eg, toxin" , "Toxic substance" .)
