Chartered Accountant to change when interrupted by 50 horsemen (7)
I believe the answer is:
cavalry
'chartered accountant to change when interrupted by 50 horsemen' is the definition.
I can't tell whether this defines the answer.
'chartered accountant to change when interrupted by 50' is the wordplay.
'chartered accountant' becomes 'CA' (abbreviation for chartered accountant).
'to' is a charade indicator (letters next to each other).
'change' becomes 'vary' (synonyms).
'when interrupted by' indicates putting letters inside (inserted letters interrupt).
'50' becomes 'l' (Roman numeral).
'vary' placed around 'l' is 'valry'.
'ca'+'valry'='CAVALRY'
Can you help me to learn more?
(Other definitions for cavalry that I've seen before include "Soldiers on horseback" , "Horse soldiers" , "Horse troops" , "Horse-soldiers" , "Mounted troops" .)
