Hesitation over a limited broadcast on various channels (10)
I believe the answer is:
multimedia
'various channels' is the definition.
'multimedia' can be an answer for 'channels' (I have seen 'several channels' mean 'multimedia' so perhaps 'channels' could also mean 'multimedia'). I'm not certain of the 'various' bit.
'hesitation over a limited broadcast' is the wordplay.
'hesitation' becomes 'um' (**).
'over' is a reversal indicator.
'broadcast' indicates anagramming the letters.
'um' in reverse letter order is 'mu'.
'a'+'limited'='alimited'
'alimited' is an anagram of 'ltimedia'.
'mu'+'ltimedia'='MULTIMEDIA'
'on' acts as a link.
Can you help me to learn more?
(Other definitions for multimedia that I've seen before include "Way of presenting data" , "Using several means of communication" , "Mail tedium (anag.)" , "several channels" .)
