In LIS not all occurrences of pronouns referring to arguments of the same sentence can be considered as pronoun copying phenomena, but only those that appear in sentence-final position. The multiple occurrences of indexical pronouns in argument position should be considered as simple pronouns. Furthermore, the category of verbs can affect the occurrence of the pronoun copying phenomenon. With agreement verbs, subject pronoun copying may appear together with object pronoun copying, specifying the relationship expressed by the verb, as shown by the example below.
ix1 giannia book 1CL(flat open 5): ‘give_book’a done ix1 ix3a
‘I gave the book to Gianni, I to him.’
