Correct spelling for the English word "dirtsider" is [dˈɜːtsa͡ɪdə], [dˈɜːtsaɪdə], [d_ˈɜː_t_s_aɪ_d_ə] (IPA phonetic alphabet).
"Dirtsider" is a slang term used to describe an individual who primarily resides or spends the majority of their time on the surface of the Earth, as opposed to living or working in outer space, particularly in relation to space exploration or colonization efforts. The term is derived from the combination of the words "dirt" (referring to the solid matter covering the Earth's surface) and "sider" (short for "sideral," which pertains to stars or outer space).
In the context of space exploration and colonization, "dirtsiders" are often contrasted with those who reside or work in space, such as astronauts or space travelers. The term is commonly used to highlight the difference in perspective and lifestyle between those individuals who are directly involved in space-related activities and those who remain firmly rooted on Earth.
While the term "dirtsider" is not widely recognized or formally accepted in dictionaries, it is frequently employed within the space industry and science fiction literature to distinguish between Earth-dwelling individuals and those who engage in space travel or reside in extraterrestrial environments. It serves as a shorthand way to describe those who are grounded in the physical reality and limitations of Earth's surface while highlighting the contrasting experiences and mindset of individuals who venture into space.
