In Versailles and chasing old court musicians (5)
I believe the answer is:
octet
'musicians' is the definition.
(I've seen this before)
'in versailles and chasing old court' is the wordplay.
'in versailles' becomes 'et' (I can't justify this - if you can you should believe this answer much more).
'and' says to put letters next to each other.
'chasing' says to put letters next to each other (some letters chase after others).
'old' becomes 'o' (abbreviation).
'court' becomes 'ct' (abbreviation used in road names).
'o' put next to 'ct' is 'oct'.
'et' after 'oct' is 'OCTET'.
Can you help me to learn more?
(Other definitions for octet that I've seen before include "A number of musicians" , "Musical group" , "Lines of verse" , "What takes members up to eighth" , "Musical work for eight" .)
