Regular -ER verbs with a small spelling tweak
Good news: these five are regular -ER verbs. They take exactly the same endings as parler (-e, -es, -e, -ons, -ez, -ent), so the formula you already know still works.
The only difference is a small spelling tweak in some forms, made so the verb keeps the same sound:
Many verbs follow the same patterns: nager and voyager (like manger), lancer and placer (like commencer), lever and se promener (like acheter), jeter (like appeler), envoyer and essayer (like payer).
