The contemplative aspect of a verb indicates that the action has not happened but is anticipated.Some verbs take a fourth aspect known as the recently complete aspect which indicates that the action has just been completed before the time of speaking or before a specified time.Tagalog grammar is the body of rules that describe the structure of expressions in the Tagalog language, the language of the Tagalog region of the Philippines.In Tagalog, there are eight basic parts of speech: verbs, nouns, adjectives, adverbs, prepositions, pronouns, conjunctions and particles. Pronouns are inflected for number; and verbs, for focus, aspect and voice.magbili and umahit are rarely used; in southern dialects of Tagalog na- is used instead of -um-.ma- is used with only a few roots which are semantically intransitive, for example, matulog (to sleep).In this system, the thematic role (agent, patient, or oblique) of the noun marked by the direct-case particle is encoded in the verb.In its default unmarked form, the verb triggers a reading of the direct noun as the patient of the clause.
Such inflections are typically irregular and must be memorized with each verb learned.The complete aspect of a verb indicates the action has been completed.The progressive aspect of a verb indicates the action has been started but not been completed or that the action is habitual or a universal fact.This does not usually happen with root words ending in pseudo-vowels such as w and y.An example of this is basa which becomes basahin rather than basain.ma- is not to be confused with ma-, the potentiative prefix for patient-triggered verb forms.
