What does earthbound mean?
"Earthbound" is an adjective with two closely related uses. In its literal sense, it describes anything that cannot or does not leave the ground — an earthbound bird that cannot fly, an aircraft kept from takeoff by weather, or humanity before the age of flight. By extension, it is applied to spacecraft and astronauts only ironically, since leaving the earth's bounds is precisely what they do. The word also has a firmly established figurative meaning: someone who is earthbound lacks imagination, ambition, or spiritual elevation, remaining tied to mundane, practical concerns. This figurative use tends to carry a mild negative connotation, contrasting the person with dreamers, mystics, or innovators who aspire to something higher. The word derives simply from "earth" plus "bound," in the sense of heading toward or confined by something, and it remains a vivid, economical way to express both physical groundedness and imaginative limitation.
Confined to or remaining on the ground; unable to fly or travel beyond the earth.
"The storm left dozens of flights earthbound across the region."
Common in aviation contexts and in discussions of pre-flight human history.
(Figurative) Lacking in imagination, vision, or spiritual aspiration; excessively practical or worldly.
"His poetry was praised for lifting the most earthbound subjects into the realm of wonder."
Carries a mildly negative connotation; frequent in literary and philosophical criticism.
Before humans ever flew, 'earthbound' was already an insult — a way of calling someone too heavy for their own dreams.

Etymology of earthbound
Earthbound is a straightforward English compound formed from "earth" (from Old English "eorthe") and "bound," here meaning confined or held fast, from Old Norse "búinn" via the past participle of "binda." The compound arose in English in the early modern period, with the literal sense of being confined to the ground appearing first and the figurative sense of spiritual or imaginative limitation developing later. It shares its first element with other native compounds such as "earthly," "earthen," and "earthquake."
How earthbound is actually used
The literal sense (not flying, not in space) is neutral and common in aviation and science fiction contexts. The figurative sense — unimaginative or spiritually limited — carries a mildly negative connotation and often appears in literary criticism and philosophical writing. The word is standard in both British and American English.
