French Past Imperative - Impératif passé

The French past imperative is very rare  because its usage is restricted to a single situation: it gives a command for something that must be done before a certain time.  Ã‚  Ã‚  Aie à ©crit ce rapport demain.  Ã‚  Ã‚  Have this report written by tomorrow.If you obey the instructions in the above example, when tomorrow comes the report will already be written, so the writing of it will be in the past, ergo, the past imperative. If you use the regular imperative, Écris ce rapport demain, the report wont yet be written when tomorrow rolls around: in accordance with the command, you will be writing it tomorrow. On the other hand, the careful use of a preposition can make all the difference - you could just say Écris ce rapport avant demain and avoid the past imperative altogether - probably another reason that it is so rare.  Ã‚  Ã‚  Soyez partis à   midi.  Ã‚  Ã‚  Leave / Be gone by noon.  Ã‚  Ã‚  Ayons fini les devoirs à   7h00.  Ã‚  Ã‚  Lets have our homework done by 7:00.The past imperative is kind of similar in nuance to the past infinitive, except that it indicates a command rather than a statement of fact.br/>Because the past imperative is so rare, theres really no need to learn how to use it, but you should be able to recognize it. How to Conjugate the Past Imperative The past imperative is a  compound conjugation, which means it has two parts: imperative  of the  auxiliary verb  (either  avoir  or  Ãƒ ªtre)past participle  of the main verb Note:  Like all French compound conjugations, the past imperative may be subject to  grammatical  agreement: When the auxiliary verb is  Ãƒ ªtre, the past participle must agree with the subjectWhen the auxiliary verb is  avoir, the past participle may have to agree with its direct object As with the present imperative, the past imperative has conjugations for only three grammatical persons:  tu,  nous, and  vous.
