The term 'Battle Field' can be broken down into three words: OPERA (5 letters), WAR (3 letters), and OPERAHOUSE (10 letters). OPERA is a form of musical theatre, usually with a story and orchestral accompaniment. WAR is an armed conflict between two or more nations or states. An OPERA house is a building specifically designed for the performance of operas. Together, these three words form the term 'Battle Field', which is a place where a battle or WAR is fought.
