Construcciones con verbo duplicado

in spanish, duplicated verb constructions are very common. in terms of its morphosyntactic codification, the duplicated verb appears in four different forms: with an auxiliary verb, without an auxiliary verb, with a plain inflected verb, and with an adverbial function. in terms of its semantics, this verbal form expresses two basic senses: iteration and emphasis. in the former, the duplicated verb denotes that a specific state of affairs, in certain linguistic contexts, is realized more than once in an undetermined way (except for states). in the latter, and within other linguistic circumstances, the duplicated verb carries only an emphatic value.
