Aloft means high up in the air, held or flying above. Overhead, and staying there.
It is formal and slightly literary, and it follows the verb, so a flag held aloft or a bird circling aloft. Sailing gave English the word, since aloft on a ship means up in the rigging, and a great deal of nautical vocabulary reached ordinary speech that way. Sport uses it for trophies, and a captain lifting a cup aloft is a fixed image.
