The Tuscan gorgia is a phonetic phenomenon governed by a complex of allophonic rules characteristic of the Tuscan dialects, in Tuscany, Italy, especially the central ones, with Florence traditionally viewed as the center.
An example: the word identificare is pronounced by a Tuscan speaker as, not as, as standard Italian phonology would require. The rule is sensitive to pause, but not word boundary, so that is realized as. In a stressed syllable,, preceded by another stop, can occasionally be realized as true aspirates, especially if the stop is the same, for example , .
Geographical distribution
Establishing a hierarchy of weakening within the class is not an easy task. Recent studies have called into question the traditional view that mutation of and is less widespread geographically than →, and in areas where the rule is not automatic, is often more likely to weaken than or. On the other hand, deletion in rapid speech always affects first and foremost wherever it occurs, but reduces less often to, especially in the most common forms such as participles. Fricativisation of is by far the most perceptually salient of the three, however, and so it has become a stereotype of Tuscan dialects. The phenomenon is more evident and finds its irradiation point in the city of Florence. From there, the gorgia spreads its influence along the entire Arno valley, losing strength nearer the coast. On the coast, and usually are not affected. The weakening of is a linguistic continuum in the entire Arno valley, in the cities of Prato, Pistoia, Montecatini Terme, Lucca, Pisa, Livorno. In the northwest, it is present to some extent in Versilia. In the east, it extends over the Pratomagno to include Bibbiena and its outlying areas, where are sometimes affected, both fully occlusive and lenited allophones being the major alternates. The Apennine Mountains are the northern border of the phenomenon, and while a definite southern border has not been established, it is present in Siena and further south to at least San Quirico d'Orcia. In the far south of Tuscany, it gives way to the lenition typical of northern and coastal Lazio.
History
The Tuscan gorgia arose perhaps as late as the Middle Ages as a natural phonetic phenomenon, much like the consonant voicing that affected Northern Italian dialects and the rest of Western Romance, but it remained allophonic in Tuscany, as laxing or voicing generally does elsewhere in Central Italy and in Corsica. Although it was once hypothesised that the gorgia phenomena are the continuation of similar features in the language that predated Romanization of the area, Etruscan, that view is no longer held by most specialists. Instead, it is increasingly accepted as being a local form of the same consonant weakening that affects other speech in Central Italy, extending far beyond, to Western Romance. Support for that hypothesis can be found in several facts:
The phonetic details of Etruscan are unknown and so it is impossible to identify their continuance.
There is no mention of the phenomenon until the 16th century, and no trace in older writing.
The gorgia is less evident in Lucca and does not exist in the far south of Tuscany or in Lazio, where Etruscan settlement was quite concentrated.
Sociolinguistic studies in Eastern Tuscany show that the gorgia competes with traditional laxing in the same postvocalic position, suggesting that the two results are phonetically different resolutions of the same phonological rule.
The gorgia shows all the characteristics of a naturally-developed allophonic rule in its alternations with full plosives.
