Generosity of types accepting needs intermittently (8)
I believe the answer is:
Here is my best explanation:
'generosity' is the definition.
(I've seen this before)
'types accepting needs intermittently' is the wordplay.
'types' becomes 'kinds' (I've seen this before**).
'accepting' is an insertion indicator.
'intermittently' means one should take alternating letters.
The alternate letters of 'needs' are 'nes'.
'kinds' placed around 'nes' is 'KINDNESS'.
'of' is the link.
(Other definitions for kindness that I've seen before include "charity", "Goodwill", "Benevolence", "Warmheartedness, consideration", "Good turn", "Compassion", "Warmheartedness, tenderness", "Consideration, warm-heartedness", "Good deed" and "Generosity towards those less fortunate".)
