FOAL, n. [Sax. fola, fole; G. füllen; D. veulen; Dan. föl; Sw. fåla; Fr. poulain; Arm. poull, pull or heubeul; W. ebawl; Corn. ebol; L. pullus; Gr. πωλος; Ch. פולא; Ar. طَفَلَ tafala, to rise or to set as the sun, to bear young, and طُفِلٌ, tofilon, pullus. The primary sense of the verb is to shoot, to cast or throw, to fall. The same verb in Heb. and Ch. signifies to unite, to fasten; in Syr. to foul, to defile; both senses from that of putting or throwing on. The verb belongs probably to the root of Eng. fall and foul, that is with a different prefix. Foal is literally a shoot, issue, or that which is cast, or which falls.]

The young of the equine genus of quadrupeds, and of either sex; a colt; a filly.
