conducas

Conducas is a term sometimes encountered in Portuguese-language texts. It is not a standard form in modern Portuguese; the correct second-person singular present subjunctive of conduzir is conduzas. Consequently, conducas is generally treated as a misspelling or a nonstandard variant, found mainly in nonstandard writing, typographical errors, or historical sources with inconsistent orthography.

Etymology and morphology: It stems from the same root as conduzir, with the subjunctive ending -as, but the conventional spelling for the tu form is conduzas, with a z in the stem, not c. This distinction is important for language learners and editors.

Usage: In standard grammar, use conduzas in present subjunctive when the subject is tu; use conduza for third-person singular or formal you. A common error is to write conducas; this should be corrected to conduzas.
