Comprehend by embracing love and kindness (10)
I believe the answer is:
compassion
'kindness' is the definition.
(I've seen this before)
'comprehend by embracing love and' is the wordplay.
'comprehend' becomes 'compass' (synonyms).
'by embracing love' becomes 'io' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'and' becomes 'n' (common abbreviation for 'and').
'compass'+'io'+'n'='COMPASSION'
Can you help me to learn more?
(Other definitions for compassion that I've seen before include "Sympathy for another's suffering" , "Kindness" , "Fellow-feeling" .)
