A rapper is an artist who performs hip-hop music, often with a focus on rhyming lyrics. The term 'rapper' can be broken down into four parts: SPIRIT (6 letters), EMCEE (5 letters), CRITIC (6 letters), and POLTERGEIST (11 letters). SPIRIT refers to the energy and enthusiasm that a rapper brings to their performance. EMCEE is another name for a rapper, and it is derived from the term 'master of ceremonies'. CRITIC is a reference to the fact that a rapper's lyrics are often subject to critical analysis. Finally, POLTERGEIST is a reference to the ghostly presence that a rapper can bring to their performance.
