Softly I can somehow produce widespread alarm (5)
I believe the answer is:
panic
'widespread alarm' is the definition.
'panic' can be an answer for 'alarm' (alarm can mean panic or worry). I'm unsure of the 'widespread' bit.
'softly i can somehow' is the wordplay.
'softly' becomes 'p' (short for piano, musical term for softly).
'somehow' indicates anagramming the letters.
'i'+'can'='ican'
'ican' with letters rearranged gives 'anic'.
'p'+'anic'='PANIC'
'produce' acts as a link.
Can you help me to learn more?
(Other definitions for panic that I've seen before include "Fear out of sixteen ac" , "Alarm - terror" , "Go to pieces" , "State of overwhelming fear" , "Great consternation" .)
