Estremenho dialect

Estremenho is a dialect of European Portuguese spoken in the former provinces of Estremadura and Beira Litoral and is part of the central-southern dialects.
The variety of Lisbon, which is used to form the basis for the pattern of European Portuguese, is within this dialect. The Lisbon dialect that serves as the basis of standard European Portuguese is the one used for official and written purposes in Angola, Cape Verde, East Timor, Guinea-Bissau, Macau, Mozambique, and São Tomé and Príncipe.

Characteristics

The Estremenhan dialects present the following characteristics:

A generalized monophthongization of the diphthong . For example, "touro" and "roupa" passes to "tôro" and "rôpa".
In certain subregions, such as saloia, a monophthongization of the diphthong occurs. For example, "manêra" instead of "maneira", although this has evolved into in the Lisbon dialect.
The predorsodental sibilants, that is, /s/ and /z/, are pronounced as in the European pattern and are well distinguished from the lower x and the j, contrary to what happens with the northern dialects.
