Most of us know that sentences and clauses can be coordinated, and that subordinating clauses can modify nouns (see restrictive relative clauses), modify verbs (see adverbial clauses) and serve as complements for verbs (see complement clauses). Also note nominalizations such as the first big constituent in "Bill's looking for the dollar under the sofa frustrated his date, Charlene."
Over the last few years, I was surprised to find out that there is another way to build multi-clausal sentences, namely clause-chaining, in which a chain of medial clauses (whose verbs don't take all of the inflections that the main clause verbs do) precedes or follows the main clause.
Among natural languages, is there another way to form multi-clausal sentences besides the ones listed above?
