Mood

A writer's attitude toward a particular topic or idea determines the mood of the verb in the sentence. This may be a somewhat difficult concept to grasp. Of the three moods of a verb, indicative, imperative, and subjunctive, pay particular attention to the latter. Most English users do not know about nor use the subjunctive, which has more exacting use in the French language.

Moods and Verbs
indicative

The CF provides essential assistance in international and domestic crises.

Where is the photocopier?


The indicative mood is the most common, and is used to state a fact or to ask a question.

imperative

March!


The imperative mood is the most martial, and is used when giving a command.
subjunctive

I demand that my request be (not is) acknowledged.

He treats the project as if it were (not was) his own.

The subjunctive mood is generally misunderstood. It is used in sentences or phrases often beginning with if or that or as if which express a wish, or desire, or requirement.
