Obs. or dial. Forms: 5 cogill, cogyl, coggul, 7 cogle, 7– coggle. [known only from 14th c.; possibly from a root *kug- with the sense ‘rounded lump,’ cf. Ger. kugel, Du. kōgel; but this is doubtful. The parallelism in form and sense to COBBLE suggests onomatopœic formation: cf. the dial. knobbly and knoggly ‘having rounded protuberances’; perh. there is also relation to cockle in sense ‘unsteady from having a rounded base’; cf. coggly, -dy = cockly, -ty.]
