On Friday satellite TV is lively (6)
I believe the answer is:
frisky
'lively' is the definition.
(I've seen this before)
'on friday satellite tv' is the wordplay.
'on' says to put letters next to each other.
'friday' becomes 'Fri' (synonyms).
'satellite tv' becomes 'sky' (I am not sure about this - if you are sure you should believe this answer much more).
'fri'+'sky' is 'FRISKY'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for frisky that I've seen before include "Frolicsome" , "Playful, full of energy" , "Animated" , "Energetically playful" , "High-spirited" .)
