Being thoughtful, care is noted somehow (11)
I believe the answer is:
considerate
'being thoughtful' is the definition.
('considerate' can be similar in meaning to 'thoughtful')
'care is noted somehow' is the wordplay.
'somehow' indicates an anagram.
'care'+'is'+'noted'='careisnoted'
'careisnoted' with letters rearranged gives 'CONSIDERATE'.
(Other definitions for considerate that I've seen before include "Kind" , "Mindful of others' well-being" , "Thinking of others" , "Showing concern for the feelings of others" , "Unselfish" .)
