Most of this sophisticated vocabulary is regular. Knowing these verbs gives you an A level vocabulary.
The verbs marked with a * have slight irregularities-do you know what they are?
Equally you should know thoroughly the irregular verbs ser, estar, dar, tener, querer, venir, poner, poder, hacer, decir, haber, traer, conducir, producir, traducir, andar and saber. Not many verbs, but they are VERY important in all their tenses.
