In linguistics, many grammars have the concept of grammatical mood, which describes the relationship of a verb with reality and intent. Many languages express distinctions of mood through morphology, by changing (inflecting) the form of the verb.
Grammatical mood is not the same thing as grammatical tense or grammatical aspect, although these concepts are conflated to some degree in many languages, including English and most other modern Indo-European languages, insofar as the same word patterns are used to express more than one of these concepts at the same time.1 Admirative mood 2 Cohortative mood 3 Conditional mood 4 Dubitative mood 5 Energetic mood 6 Eventive mood 7 Generic mood 8 Hypothetical mood 9 Imperative mood 10 Indicative mood 11 Declarative mood 12 Interrogative mood 13 Jussive mood 14 Negative mood 15 Optative mood 16 Potential mood 17 Presumptive mood 18 Subjunctive mood
