eDIL - Electronic Dictionary of the Irish Language

The electronic Dictionary of the Irish Language (eDIL) is a digital dictionary of medieval Irish. It is based on the ROYAL IRISH ACADEMY’S Dictionary of the Irish Language based mainly on Old and Middle Irish materials (1913-1976) which covers the period c.700-c.1700. The current site contains revisions to c.4000 entries and further corrections and additions will be added in the coming years.

MONGACH 'long-haired, hairy' is an adjective applied in medieval Irish literature to Samson, Christ, horses, wolves, bulls and sheep, amongst other things. In its extended uses, it can refer to vegetation (MONGACH MER is 'hemlock') and RÉTLU MONGACH, literally 'a hairy star', is the early Irish term for a comet.

CARPAT was 'war-chariot' but, presumably because the shape of the chariot-body resembled the opposable parts of the mouth, CARPAT ÚACHTARACH and CARPAT ÍCHTARACH could also mean the upper and lower palate. In addition, there was an intriguing Old Irish legal term CARPAT AR IMRAM 'chariot on the move', which seems to have referred to a person who had stock but no land.

DRUIM(M) 'back' appears in statements claiming that the death of an important figure 'broke the back' of the land with which he was associated. Poet Giolla Brighde Mac Con Midhe, for example, states that Ireland's back was broken ('Banbha do brisiodh a druim') when Maoileachlainn Ó Domhnaill was slain by the Normans in 1247. And a medieval Irish adaptation of a Classical text goes a step further to claim that the world's back was broken when Memnon died.
