To some in trouble, feelings are needed (8)
I believe the answer is:
emotions
'feelings are needed' is the definition.
I can't judge whether this definition defines the answer.
'to some in trouble' is the wordplay.
'trouble' indicates anagramming the letters.
'to'+'some'+'in'='tosomein'
'tosomein' with letters rearranged gives 'EMOTIONS'.
Can you help me to learn more?
(Other definitions for emotions that I've seen before include "Intense mental feelings, like love or hate" , "Anger and love, say" , "Strong feelings" , "instinctive feelings" , "Feelings provoked by noise, Tom" .)
