Cautious and full of concern for the Speaker (7)
I believe the answer is:
careful
'cautious' is the definition.
(synonyms)
'full of concern for the speaker' is the wordplay.
I cannot quite see how this works, but
'concern' could be 'care' (synonyms) and 'care' is found within the answer.
The remaining letters 'ful' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for careful that I've seen before include "'Prudent, cautious (7)'" , "Thrifty" , "Thorough" , "Painstaking" , "Watch it!" .)
