Enclosures of this kind are among the most common and least understood monument types in Ireland, ranging from prehistoric ring ditches to early medieval farmsteads ringed by earthen banks, the latter sometimes called raths or ringforts, built to demarcate a household's territory and perhaps to pen livestock overnight. That Knocknahila More has one is not itself surprising; Clare is dense with such features. What is quietly striking is how little has been formally published about this particular example, its form, its date, and its condition left largely unexamined in any accessible record.

The name Knocknahila More carries traces of its own history. In Irish, cnoc na coille, or variations on it, typically points to a hill associated with woodland, and the suffix mór simply means great or large, distinguishing the townland from a smaller neighbour. Whether the enclosure sits on any elevated ground, or how it relates to the broader archaeology of the area, remains unclear from available sources. Clare's interior is scattered with earthworks that have never been excavated, surviving only as crop marks or faint rises in improved pasture, their interiors long since levelled by ploughing or obscured by scrub. This one, for now, belongs to that quietly ambiguous category of places that are known to exist without yet being fully known.
