I'm looking for German verbs with a bisyllabic root that have are stressed on their first syllable. But verbs like ändern or wechseln and also eignen don't count, which would be verb roots that end in -er, -el or -en. Compound verb roots and verb roots with a suffix don't count. Stressed separable prefixes clearly don't count either (e.g. anfangen).
Basically the two verbs arbeiten and heiraten seemed odd to me in that they are similar in sharing the above characteristics, but are unlike any other verb I tried to think of. Are there more verbs like those two?
