The word Deabadh comes from the ancient Celtic sagas that are centred on Fionn and the Fianna (Warriors). A cycle of legends have gathered around Fionn and his men that were equally popular with the Gaels of both Ireland and Scotland. We read of their exploits in stories and poems preserved in the earliest Irish manuscripts.
Most of the Celtic sagas revolved around battles or hunts. The most famous chase of all is, however, not that of deer or boar but of a woman and a man. This is called Toraiocht (journey) of Diarmuid and Grainne.
The literal translation of Deabadh is urgency, sense of purpose, hurry, and in ancient Scottish-battle. Within the Toraiocht Deabadh is used to cover both urgency and sense of purpose, however, it is also means much more. A combination of excellent planning skills, strong negotiation skills, raw physical courage, the ability to come up with surprises that no one had envisaged (to think outside the box), intellectual rigour, pragmatism and an element of chutzpah - to use a non Irish expression.
All the above is inherent with Deabadh as a concept and a way of life.
