Passe compose infinitif present infinitif passe . J'ai voulu terminer avant midi. .... This sentence would be passe compose and it would translate as: .......... I wanted to finish by midday. Je veux avoir terminé avant midi. .... This sentence would be past infinitive and it is translated as: .......... I want to finish by noon. Je vex terminer avant midi. ..... This sentence would be present infinitve and would it translate as: .......... I want to finish by noon. . I am confused with the difference between present and past infinitive. Also would it be correct to translate the past infinitive (Je veux avoir terminé avant midi) as I wanted to finish by noon. From the translations i don't see how past infinitive relates to the past. Any help is greatly appreciated.
