Canada nervous about what's broadcast by a snaky type (8)
I believe the answer is:
anaconda
'a snaky type' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'canada nervous about what's broadcast' is the wordplay.
'nervous' indicates anagramming the letters (shaking).
'about' indicates putting letters inside.
'what's broadcast' becomes 'on' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'canada' is an anagram of 'anacda'.
'anacda' enclosing 'on' is 'ANACONDA'.
'by' is the link.
Can you help me to learn more?
(Other definitions for anaconda that I've seen before include "Large semiaquatic snake" , "One may put squeeze on" , "1 of 21 [SNAKES]" , "Strangler" , "cold-blooded killer" .)
