It is also a highly irregular French -re verb that doesn't follow regular conjugation patterns. Croire Is a Highly Irregular French Verb Within irregular French -re verbs, there are a few verbs that demonstrate patterns, including verbs conjugated like prendre, battre, metter and rompre, and verbs ending in -craindre, -peindre and -oindre. Croire, to the contrary, is one of those highly irregular French verbs with conjugations so unusual and unwieldy that they don't fall into any pattern. They are so irregular, you have to memorize them to use them correctly. These very irregular -re verbs include: absoudre, boire, clore, conclure, conduire, confire, connaître, coudre, croire, dire, eacute;crire, faire, inscrire, lire, moudre, naître, plaire, rire, suivre and vivre. Try working on one verb a day until you've mastered them all. The table below shows the irregular simple conjugations of croire. Note that the table does not include compound conjugations, which consist of a form of the auxiliary verb avoir and the past participle. Be careful when you say or spell the third person plural ils form, which is ils croient not ils croivent. Many people, even the French, make this mistake. 'Croire' Meanings and Uses The primary meaning of croire is “to believe.” It’s often followed by que, as in:Je crois qu’il viendra. = I believe he will come. Croire is not used with the subjunctive in the affirmative form, even if it’s followed by que. Granted it fulfills all the conditions for using the subjunctive, but, like je pense que + indicative, it’s an exception. Why? Because whoever is speaking really believes/thinks this is a reality, not a supposition. Croire is used in the sign-off at the end of formal business letters: Veuillez croire, chère Madame, à l’expression de mes salutations distinguées. > Sincerely yours 'Croire en' vs. 'Croire à' When you believe in someone or in God, use “coire en.” Il croit en Dieu. = He believes in GodJe crois en toi. = I believe in you. When you believe in something, like an idea, or a myth, use “croire à.” Tu crois au Père-Noêl ? = Do you believe in Santa?Ton idée de travail, j’y crois. = I believe in your work idea. Pronominal: 'Se Croire' When used in the reflexive form, the verb means to see oneself as, to believe oneself to be. Elle se croit très intelligente. = She thinks she's very smartIl s'y croit déjà. = He believes he's there already.
