Benevolent domestic and international board (10)
I believe the answer is:
charitable
'benevolent' is the definition.
(similar in meaning)
'domestic and international board' is the wordplay.
'domestic' becomes 'char' (term for a domestic servant or cleaner).
'and' says to put letters next to each other.
'international' becomes 'i' (abbreviation eg in IMF).
'board' becomes 'table' (synonyms).
'char'+'i'+'table'='CHARITABLE'
(Other definitions for charitable that I've seen before include "Generous" , "Thoughtful" , "Inspired by the will to do good for others" , "Kind" , "Big-hearted" .)
