Conjunctions in Italian constitute an open class: the same elements can often have the function of conjunctions, prepositions or adverbs. Consider the following:
For these classes, as far as possible, application tests have to be employed:
In grammars, no agreement is reached as to the inclusion of some elements in the conjunction or the adverb class (e.g. `anche', `pure', `dunque', `pertanto').
In some recent linguistic theories, all these elements go into the wider class of connettivi (`connectives'), which link various parts of a text.
In tagging Italian, the problem of subordinating multiwords has to be dealt with, e.g. ``dal momento che''.
