How German verb conjugation works
German verbs conjugate by dropping the infinitive ending and adding a personal ending to what is left. Take the infinitive, strip the final -en, and you have the stem: machen becomes mach-. The six present endings then attach to it, and they are the same for almost every regular verb you will meet. Two wrinkles account for most mistakes. A stem ending in -t or -d takes a linking -e- before the ending, so arbeiten gives du arbeitest, not du arbeitst. And strong verbs change their stem vowel in the du and er/sie/es forms only — fahren becomes du fährst but wir fahren. The Perfekt is built differently again: haben or sein plus the past participle. The full rules, including which verbs take sein, are on the guide linked below.
Regular verbs share six present-tense endings — -e, -st, -t, -en, -t, -en — and the full set of rules, including the stem-vowel changes and the Perfekt, is on the guide: how German verb conjugation works.
