tratada

Tratada is the feminine singular past participle of the verb tratar in Portuguese and Spanish. It is used as an adjective and as a passive participle to indicate that something has undergone treatment, handling, or discussion. The form agrees with the gender of the noun it describes, for example agua tratada (feminine) or tema tratado (masculine).

In both languages, tratar originates from Latin tractare, and the participle tratada derives from that verb through the evolution of Romance languages. As an adjective, tratada commonly describes processed or prepared items, areas of study, or topics that have been addressed. For instance, água tratada means water that has been treated, and o assunto tratado refers to the subject that has been dealt with. The word can also appear in phrases describing people or objects that have undergone medical, chemical, or administrative treatment, depending on the context.

Usage notes: when referring to a feminine noun, the form tratada is used; masculine nouns take tratado, and plural forms are tratadas (feminine) or tratados (masculine). The term can appear in formal writing to indicate completion of a treatment or handling process, and it may also function within compound tenses, following appropriate auxiliary verbs.
