This is a regular -er verb, but the stem is written engage- before endings that begin with -a- or -o- (to indicate that the -g- is a "soft" /ʒ/ and not a "hard" /ɡ/). This spelling-change occurs in all verbs in -ger, such as neiger and manger.

engager

1. Alternative form of engagier

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 /dʒ/ sound intact. Old French conjugation varies significantly by date and by region. The following conjugation should be treated as a guide.
