French Subjunctive Irregular Conjugations

While not as difficult as using the French subjunctive, conjugating irregular and stem-changing verbs into the subjunctive can be a little tricky.Stem-changing verbs and most irregular verbs follow the same pattern as regular verbs for the singular conjugations (je, tu, il/elle/on) as well as the third person plural (ils/elles): the subjunctive stem is derived from the present tense conjugation of ils. boire envoyer prendre venir present tense: ils boivent envoient prennent viennent stem boiv- envoi- prenn- vienn- subjunctive endings: boire envoyer prendre venir ... que je -e boive envoie prenne vienne ... que tu -es boives envoies prennes viennes ... quil/elle/on -e boive envoie prenne vienne ... quils/elles -ent boivent envoient prennent viennent However, the nous and vous forms of the subjunctive find their stems in the present tense conjugation of nous: present tense: nous buvons envoyons prenons venons stem buv- envoy- pren- ven- subjunctive endings : ... que nous -ions buvions envoyions prenions venions ... que vous -iez buviez envoyiez preniez veniez This two-stem subjunctive pattern applies to all stem-changing verbs as well as all but seven irregular verbs.Five verbs have irregular subjunctive stems but take the same endings as above: One stem Two stems* faire pouvoir savoir aller vouloir stem(s) fass- puiss- sach- aill- / all- veuill- / voul- ... que je (j) fasse puisse sache aille veuille ... que tu fasses puisses saches ailles veuilles ... quil/elle/on fasse puisse sache aille veuille ... que nous fassions puissions sachions allions voulions ... que vous fassiez puissiez sachiez alliez vouliez ... quils/elles fassent puissent sachent aillent veuillent *These two verbs have different stems for je/tu/il/ils and nous/vous.And finally, two verbs have irregular stems as well irregular endings: avoir tre ... que je (j) aie sois ... que tu aies sois ... quil/elle/on ait soit ... que nous ayons soyons ... que vous ayez soyez ... quils/elles aient soient
