The purpose and goal of the research is to examine the relationship between Irish language and Gaeltacht identity. The article analyses data from the qualitative research which was carried on through the medium of semi-structured interviews and focus-group discussion in the Republic of Ireland. All our findings are based on the evaluations made from the point of view of external, non-Irish researcher. Our findings showed that there is still a substantial relationship between Irish language and Gaeltacht/Gaelic ethnocultural identity. Irish language is an essential element of cultural and national identity and for many people living in Gaeltacht it transcends culture. We assume that language determines our individual/personal identity as well as collective identity. We also highlight some of the most challenging aspects of language revitalization and sustainability of Gaeltacht communities. Identity and language evolve in time so there is a huge space for further research pertaining to the question of language revival and its future which could be examined in the long-term horizon.
