Source: vocabulary for the high school studentBilly Budd put an end to the discord aboard the "Rights-of-Man." He was an excellent peacemaker.
The blue part makes me confused because [aboard] is usually used when talking about ships or planes.
aboard = on a ship, plane or train
Rights-of-Man = name of a book
The blue part means [on the book] which is odd to me. Would you please help me with that?
