1. Pertaining to a king; kingly; royal: as, a regal title; regal authority; regal pomp.

3. Royalty; royal authority.
4. n. A small portable organ, much used in the sixteenth and seventeenth centuries, consisting of one or sometimes two sets of reed-pipes played with keys for the player's right hand, with a small bellows for the left hand. Its compass included only a few tones. In many cases the instrument was made to shut up within covers, like a large book: hence the name Bible-organ. If there was but one pipe to each note, the instrument was called a single regal, if two pipes to each note, a double regal. The invention of the regal is often erroneously ascribed to Roll, an organ-builder of Nuremberg, in 1575; the instrument was common in England in the reign of Henry VIII. It is now obsolete, but the name is still applied in Germany to certain reed-stops of the organ. In England a single instrument was usually called a pair of regals.
5. n. An old instrument of percussion, composed of sonorous slabs or slips of wood. It was a sort of harmonica, and was played by striking the slips of wood with a stick armed with a ball or knob.
