Abstract EN:

The dialectologist is a navigator who discovers new lands with the help of maps that he himself has established from field work. In the "ile-de-france", the slight gap between the national and rural language has posed specific problems of method : the amount of information collected is not proportional to the time spent ; in fact, it is the opposite (2000 questions, 76 points, 1000 maps). Surrounding paris on three sides, the atlas of "l'ile-de-france" helps to better understand the relationship between the present day french language and the "dialects" from which it originated. But synchronic maps have a constant need of the diachrony and texts. It has been necessary to make an inventory of the dialectal litterature to analyse "the words and things", examine the lexico-semantic fields, re-position the "ile-de-france in the vast ensemble of central languages. Lastly the geolinguist must be able to go from micro map reading to macro map reading, change his analytical approach, see the romance language as a whole, lexicosemantic hispanic studies, the participation in the roman european linguistic atlas, are graved in the researcher's logic. The linguistic maps are indeed the formal expression of field work methods ; however, this is not true for the territory. Field work can modify it, radically change itand open new and different perspectives.
