Care about first person to enter retirement (10)
I believe the answer is:
solicitude
'care' is the definition.
(thesaurus)
'about first person to enter retirement' is the wordplay.
I cannot quite see how this works, but
'about' could be 'c' (abbreviation for 'circa') and 'c' is located in the answer.
'first' could be 'i' (I in Roman numerals eg Elizabeth I) and 'i' is found in the answer.
The remaining letters 'solitude' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for solicitude that I've seen before include "Care, concern" , "Feeling of excessive concern" .)
