Toponymy is the scientific study of place names (toponyms), their origins, meanings, use and typology. The word "toponymy" is derived from the Greek words tópos (τόπος) ("place") and ónoma (ὄνομα) ("name"). Toponymy is itself a branch of onomastics, the study of names of all kinds. Toponymy is distinct from (though often confused with) etymology, which is the study of the origins of words.

A toponymist is one who studies toponymy. According to the Oxford English Dictionary, the word "toponymy" first appeared in English in 1876; since then, toponym has come to replace "place-name" in professional discourse among toponymists. It can be argued that the first toponymists were the storytellers and poets who explained the origin of specific place names as part of their tales; sometimes place-names served as the basis for the etiological legends. The process of folk etymology usually took over, whereby a false meaning was extracted from a name based on its structure or sounds. Thus, the toponym of Hellespont was explained by Greek poets as being named after Helle, daughter of Athamas, who drowned here as she crossed it with her brother Phrixus on a flying golden ram. The name, however, is probably derived from an older language, such as Pelasgian, which was unknown to those who explained its origin. George R. Stewart theorized, in his book Names on the Globe, that Hellespont originally meant something like "narrow Pontus" or "entrance to Pontus," "Pontus" being an ancient name for the region around the Black Sea, and by extension, for the sea itself.

Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American recording artist, entertainer, and businessman. Often referred to as the King of Pop, or by his initials MJ, Jackson is recognized as the most successful entertainer of all time by Guinness World Records. His contribution to music, dance, and fashion, along with a much-publicized personal life, made him a global figure in popular culture for over four decades. The seventh child of the Jackson family, he debuted on the professional music scene along with his brothers as a member of The Jackson 5 in 1964, and began his solo career in 1971.

In the early 1980s, Jackson became a dominant figure in popular music. The music videos for his songs, including those of "Beat It", "Billie Jean", and "Thriller", were credited with transforming the medium into an art form and a promotional tool, and the popularity of these videos helped to bring the relatively new television channel MTV to fame. Videos such as "Black or White" and "Scream" made him a staple on MTV in the 1990s. Through stage performances and music videos, Jackson popularized a number of complicated dance techniques, such as the robot and the moonwalk, to which he gave the name. His distinctive musical sound and vocal style influenced numerous hip hop, post-disco, contemporary R&B, pop and rock artists.
