The dingle of dingleberry has been connected by some etymologists to the English word dung from PIE *dhengh- 'to press, curve, bend, cover' (Russian дуга (duga) 'arc'). The Old Irish word daingean 'strong, fast/fixed; fortress' is from a PIE homonym *dhengh- 'to accomplish; fixed' (Greek ταχυς (takhus) 'quick, fast', Russian дяга (djaga) 'leather strap'). [Pokorny IEW 250.] The sense of dingle as 'dell' is attested first in Middle English in the 13th century, which is about the time that the English placename came to be used for the Irish city. The Gaelic An Daingean Uí Chúis 'the fortress of O'Cush' has been used for about the same amount of time.
