The Verb Devoir in the Conditional Tense by Bruce Sallee and David Hebert
The verb devoir takes on a unique meaning when used in the conditional tense. It is the equivalent of the English construction “should” or “ought to,” as in “I should go to the store.”
Je devrais lui passer un coup de fil. |
I should call him. |
Il devrait travailler plus. |
He should work more. |
When placed in the conditional, therefore, devoir implies that there is some doubt as to whether the event will actually occur. It imports an obligation of an almost moral nature; quite often, there will be an unspoken “but,” implying that the event may, in fact, never take place at all. In some grammatical circles, using devoir in the conditional is known as the “tense of regret” for that very reason.
Devoir has an irregular future stem, so it uses devr- as the stem in the conditional. Remember not to confuse the conditional conjugation of devoir with the imperfect conjugation, because they each have completely different meanings. In the imperfect tense, devoir means “used to have to.” It still implies the obligation. Only when the statement is cast in the conditional does the necessary doubt enter the picture to trigger the same response as a “should” construction does in English.
