The following project aims to study the relationship between the suffix -ado and its denominal derivations, in view of your diachronic route. The corpus of this work will consist of articles taken from the Houaiss Electronic Dictionary, in which -ado holding function of derivational suffix and also in the same morpheme which became part of the radical in derived denominal words. It is noteworthy that the entries will undergo a standard for analysis of the word autonomy in relation to the participial form, given the high number of inflectional data only. The words collected will be paraphrased, in order to describe the diversity of semantic values of this suffix. The values will be considered by the semantic values of the dictionary and values described by the authors of the literature, for example, Rio-Torto (2004). Some online synchronic and diachronic corpora are consulted to examine the use of words studied, such as the Corpus of Portuguese and the website Google Books. The collection of the entries will go through a classification according to the different semantic values found by the suffix, and its vestiges in the present derivations. Once used a diachronic approach in conjunction with the synchronous, it will seek a genealogy of the suffix -ado, showing the semantic changes of which suffered in the various synchronicities, regarded as inevitable components of contemporary Portuguese.
