Kindly feeling not hard to place (4,4)
I believe the answer is:
soft spot
'kindly feeling' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'not hard to place' is the wordplay.
'not hard' becomes 'soft' ('soft' is the opposite to 'hard').
'to place' becomes 'spot' (synonyms).
'soft'+'spot'='SOFT SPOT'
Can you help me to learn more?
(Other definitions for soft spot that I've seen before include "Sentimental fondness" , "Feeling of affection towards person - not hard" , "Affectionate weakness for (someone/something)" , "Sentimental affection" , "showing fondness" .)
