Morse vacantly needing help to raise sources of information (5)
I believe the answer is:
media
'sources of information' is the definition.
(I've seen this before)
'morse vacantly needing help to raise' is the wordplay.
'morse vacantly' becomes 'm' (I can't justify this - if you can you should believe this answer much more).
'needing' is a charade indicator (letters next to each other).
'help' becomes 'aide' (aide is a kind of help).
'to raise' says the letters should be written in reverse.
'aide' written backwards gives 'edia'.
'm'+'edia'='MEDIA'
Can you help me to learn more?
(Other definitions for media that I've seen before include "The 14, for example" , "Press, TV, radio" , "Television, papers, etc" , "oils as examples" , "Eg, newspapers, TV" .)
