How would you conjugate manger for er nous and what is the conjugation for on

Nous mangeons
On mange
“Mange” is conjugated like all -er verbs. The “nous” form is special, however, because an “e” has to be added before the ending “ons.” Otherwise, the word would be “mangons,” pronounced with a hard “g” sound like in “girl.” The form of “on” is the same as “il” and “elle.”

To conjugate manger for nous you simply drop the er and add a ons in its place
