People, nowadays, have ways of accepting service (7)
I believe the answer is:
moderns
'people' is the definition.
The answer is an example.
'nowadays have ways of accepting service' is the wordplay.
I cannot really understand how this works, but
'of' could be 'o' and 'o' is found within the answer.
'service' could be 'rn' (abbreviation for Royal Navy) and 'rn' is found in the answer.
'ways' could be 'es' (east and south - two directions) and 'es' is located in the remaining letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for moderns that I've seen is " People today".)
