Click the gloss button for the correct meaning of each sentence and the button to the right to see if you typed in the correct form. The first one has been completed for you as a pattern. Conclusion Notice that all the clauses, nouns, verbs, etc. connected by conjunctions are semantically equal in the sentences introduced thus far.

Subordination is therefore a purely syntactic phenomenon.
