Repeatedly asking to be careful (10)
I believe the answer is:
solicitous
'careful' is the definition.
(similar in meaning)
'repeatedly asking to' is the wordplay.
I cannot quite understand how this works, but
'to' is present in the answer.
This explanation may well be incorrect...
'be' acts as a link.
Can you help me to learn more?
(Other definitions for solicitous that I've seen before include "Showing concerned attention" , "Anxious - concerned" .)
