Friend on TV has hope dashed live (6)
I believe the answer is:
phoebe
'friend on tv' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'hope dashed live' is the wordplay.
'dashed' is an anagram indicator.
'live' becomes 'be' (synonyms).
'hope' with letters rearranged gives 'phoe'.
'phoe'+'be'='PHOEBE'
'has' acts as a link.
Can you help me to learn more?
(Other definitions for phoebe that I've seen before include "flycatcher" , ""moony" woman" , "Titan, daughter of Uranus -- satellite of Saturn" , "Old poetic name for moon, and satellite of Saturn" , "Daughter of Uranus and Gaia" .)
