Conjugation

This verb conjugates as a first-group verb ending in -er. In the present tense an extra supporting e is needed in the first-person singular indicative and throughout the singular subjunctive, and the third-person singular subjunctive ending -t is lost. In addition, g becomes j before an a or an o to keep the /d?/ sound intact. Old French conjugation varies significantly by date and by region. The following conjugation should be treated as a guide.
