"Temple" in Irish placenames derives from the Latin "templum" by way of early Christian usage, and typically marks the location of a church or chapel, often one of considerable age. The "more" element, from the Irish "mór", simply means large or great, suggesting this was once a place of some local significance, though what physical traces remain at ground level is not currently documented in the available record.

The name Knockagarraun itself is worth a moment's attention. "Cnoc" is the Irish word for a hill or rounded height, and "garraun" likely derives from "gearrán", meaning a gelding or work horse, a type of placename element that appears across Connacht and often reflects the agricultural memory of a landscape. Together, the two names, one marking a probable early Christian site, the other preserving a glimpse of rural land use, sit quietly in this corner of Mayo, pointing to layers of occupation and activity that have yet to be fully examined or published.
