Tense of verbs

Tense–aspect–mood, commonly abbreviated tam and also called tense–modality–aspect or tma, is the grammatical system in a language that covers the expression of tense(location in time), aspect (fabric of time – a single block of time, continuous flow of time, or repetitive occurrence), and mood or modality (degree of necessity, obligation, probability, ability).[1] In some cases, evidentiality (whether evidence exists for the statement, and if so what kind) may also be included.
