What one needs here — news broadcast in Arabic (6)
I believe the answer is:
answer
'what one needs here' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'news broadcast in arabic' is the wordplay.
'broadcast' is an anagram indicator (letters scattered or cast around).
'in' means one lot of letters goes inside another.
'arabic' becomes 'ar' (abbreviation in Chambers).
'news' anagrammed gives 'nswe'.
'nswe' put inside 'ar' is 'ANSWER'.
Can you help me to learn more?
(Other definitions for answer that I've seen before include "'Daisy, Daisy, give me your ...... do'" , "Respond" , "Acknowledge" , "Write back" , "fit" .)
