shoal

shoal: English has two distinct words shoal. ‘Shallow area’ [16] is descended from the Old English adjective sceald ‘shallow’, which in turn came from prehistoric Germanic *skaldaz. (English shallow [15] is related, although it is not clear precisely how.) Shoal of fish [16] is simply a reborrowing of Middle Dutch schōle, which had earlier been taken over as school.

shoal (n.1)

"place of shallow water," c. 1300, from Old English schealde (adj.), from sceald "shallow," from Proto-Germanic *skala- (cognates: Swedish sk?ll "thin;" Low German schol, Frisian skol "not deep"), of uncertain origin. The terminal -d was dropped 16c.

shoal (n.2)

"large number" (especially of fish), 1570s, apparently identical with Old English scolu "band, troop, crowd of fish" (see school (n.2)); but perhaps rather a 16c. adoption of cognate Middle Dutch schole.

shoal (v.)

"assemble in a multitude," c. 1600, from shoal (n.2). Related: Shoaled; shoaling.
