The term 'BIG SHOWCASE' can be broken down into three parts: EXPO (4 letters), VIDEO (5 letters), and SOLO (4 letters). An EXPO is a large exhibition or fair, usually featuring displays of products or services. A VIDEO is a recording of moving images, typically accompanied by sound, that can be viewed on a television, computer, or other device. A SOLO is a performance by a single person, such as a singer or musician. Together, these three words form the phrase 'BIG SHOWCASE, ' which could refer to a large event featuring exhibitions, videos, and SOLO performances.
