Provides continuity in cat broadcast (5)
I believe the answer is:
links
'provides continuity' is the definition.
I can't tell whether this definition defines the answer.
'cat broadcast' is the wordplay.
'cat' becomes 'lynx' (lynx is a kind of cat).
'broadcast' indicates a 'sounds like' (homophone) clue (how the word might sound on the radio or TV).
'lynx' sounds like 'LINKS'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for links that I've seen before include "(Seaside) golf course - connections" , "Bonds" , "course for sportspeople" , "Golf course by the sea" , "Golf-course" .)
