 The village is a little off the ancient Roman road, now D52, roughly North-South in direction.An ancient and legendary explanation is that the name comes from the Latin form ("Ledera") of the name of a local brook called the "Leder".This explanation, given in tome II, page 572 of Flandria Illustrata (1641), and though doubtful, is also provided for the name of nearby village Lederzeele.
