there (adv., expletive)
Both functions are illustrated in this sentence: There there is some snow. There is some snow there on the lawn. At the front of the sentence, when two theres appear together, the first is always the adverb, the second the expletive. When the theres are not contiguous, as in the second example, the first one, close to its verb, is always the expletive and the one tagging along anywhere after the verb is always the adverb. See DUMMY SUBJECTS; THEIR; THERE IS.
