Below or beneath in position; subject to the authority of.
Etymology
Modern English under comes from Old English under "beneath, among, before," from Proto-Germanic *under, from PIE *n̥dʰer- meaning "under, below." The n̥ represents a syllabic nasal that developed differently across branches. Latin infra "below" and inferus "lower" come from a related form, giving English inferior, infernal, and infrastructure. Sanskrit adhás "below" is another cognate. The PIE root is essentially the counterpart to *uper "over." Within Germanic, German unter, Dutch onder, and Old Norse undir are direct siblings. English has made this preposition extraordinarily productive: understand (originally "to stand among"), undertake, undergo, undermine, underworld, and scores more. The word underdog emerged in the 19th century from dogfighting, while understand may derive from the idea of "standing close to" or "standing under" the meaning of something.

Did You Know?
The word understand literally means "to stand under." But this likely didn't mean "beneath" — Old English under also meant "among, between." To understand was to stand among the facts, to be in the middle of the meaning. The same PIE root gave Latin infernus "the underworld," source of English infernal.
