a circle or ring; a small ring or ringlet (archaic or regional usage).
From 'ring' with the diminutive suffix '-le' (like 'sparkle' from 'spark'). It's an old or dialectal English word rarely used in modern standard English.
This is a ghost word—it haunts old texts but almost nobody uses it anymore. English has a graveyard of these diminutive words: 'ringlet' survived (a curl), but 'ringle' didn't. Language is constantly pruning.
