MENTOR: Previous winners of the Hunger Games are lifelong mentors to the tributes from their district each year.
MOCKINGJAY: When male jabberjays mated with female mockingbirds they produced mockingjays. These black-and-white birds don't have the ability to record conversations but they can mimic human sounds and are able to memorize songs. Katniss wears a mockingjay pin inside the arena as her tribute token.
MUTTATION: Animals genetically altered and manipulated by the Capitol to be used as weapons. Examples include jabberjays and tracker jackers.
PANEM: "A shining Capitol ringed by thirteen districts," Collins writes of her books' setting. Panem is located in what used to be known as North America after a series of disasters, including droughts, storms, fires and encroaching seas.
PREP TEAM: Each tribute is assigned a team of stylists to help them look their best (according to Capitol standards) at various public appearances related to the Hunger Games. The goal: to lure sponsors to send the tributes gifts inside the arena.
PRESIDENT SNOW: The longtime totalitarian leader of Panem.

THE SEAM: The most impoverished area of District 12 and Katniss's home. It borders the uninhabited(and off-limit) woods, where she and Gale hunt for much-needed food.
SPONSOR: During the Hunger Games, a tribute's mentor is responsible for procuring needed – and very expensive – items with donations from supporters known as sponsors. A sponsor can be a wealthy Capitol citizen who is impressed with a tribute's performance or members of the community of his or her district, pooling their resources.
TESSERA: Needy district kids can apply for extra food for themselves and/or family members in exchange for their names being added additional times at the upcoming reaping.
TOKEN: Each tribute is allowed to bring something to the Hunger Games that represents their District and reminds them of home. Katniss's token is the mockingjay pin.
TRACKER JACKER: Muttations that resemble wasps, whose painful stings induce intensely frightening hallucinations.
TRIBUTE: A participant, aged 12 to 18, of the Hunger Games.
