Usage of the Imperfect Subjunctive
The subjunctive imperfect is very rarely employed in French; generally it only appears in literature and is viewed as archaic. It can in all instances be replaced by the subjunctive present. The subjunctive imperfect is employed in any instance in which the subjunctive is required, provided the trigger verb is in a past tense. In the example "Il fallait que le garçon allât à l'école", the subjunctive trigger verb "falloir" is in the imperfect, thus "aller" has been conjugated in the subjunctive imperfect. French speakers would normally express this as "Il fallait que le garçon aille à l'école", where "aller" has been conjugated in the present subjunctive.
