One of the remarkable characteristics of the Basque verb is the fact that only a very few verbs can be conjugated synthetically (i.e. have morphological finite forms); the rest only have non-finite forms, which can enter into a wide variety of compound tense structures (consisting of a non-finite verb form combined with a finite auxiliary) and are conjugated in this way (periphrastically). For example, 'I come' is "nator" (a synthetic finite form), but 'I arrive' is (a periphrastic form, literally 'arriving I-am').
