Auxiliary-verb Sentence Examples
Whereas the Hebrew verb is devoid of real tenses, and only expresses an action as completed or as in process without indicating time past, present or future, Syriac has by the help of an auxiliary verb constructed a set of tenses.
In compound tenses we need to include the direct object between the subject and the auxiliary verb.
One other important note when conjugating reflexive verbs is that in past tenses where the verb requires an auxiliary verb such as passé composé, reflexive verbs always take être.
