The state or relationship of being an accomplice; the condition of being a partner in crime or wrongdoing.
From accomplice (from Old French complice, likely from Latin com- 'with' +plicare 'to fold/involve') + -ship suffix meaning 'state or condition of.'
The -ship suffix is wonderful for abstract relationships (friendship, leadership, accompliceship)—it names the bond itself, and accompliceship specifically captures how people become entangled in shared guilt.
