This document discusses result clauses and purpose clauses in sentences. Result clauses express the effect or consequence of information in an independent clause and often use structures like "such a/an noun that" or "so adj/adverb that." Purpose clauses express the action in an independent clause to emphasize it and often use modals or conjunctions like "so that" or "in order that." Farmers, for example, use chemical pesticides so that or in order that they can get higher crop yields.
