In linguistics, many grammars have the concept of grammaticalmood which describes the relationship of the verb with reality and intent. Many languages express distinctions of mood through morphology, bychanging ( inflecting) the form of the verb ( Warriner,1982:159, Palmer,1988:151 and Crystal, 1991:223)Currently identified moods include: conditional sentences, imperative,injunctive, negative, optative, potential, subjunctive and so on. Infinitive isa category apart from all these finite forms, and so are gerunds andparticiples. It should be noted that not all of the moods listed above are clearlyconceptually distinct and that individual terminology varies from languageto language even when two different moods exist in the same language, their respective usages may be blurred, or may be defined by syntacticrather than semantic criteria. We can determine some commoncharacteristics of the imperative mood found in this kind of structures inFrench and English.
