As sign of the infinitive, to had originally the use of last
   defined, governing the infinitive as a verbal noun, and connecting it
   as indirect object with a preceding verb or adjective; thus, ready to
   go, i.e., ready unto going; good to eat, i.e., good for eating; I do my
   utmost to lead my life pleasantly. But it has come to be the almost
   constant prefix to the infinitive, even in situations where it has no
   prepositional meaning, as where the infinitive is direct object or
   subject; thus, I love to learn, i.e., I love learning; to die for one's
   country is noble, i.e., the dying for one's country. Where the
   infinitive denotes the design or purpose, good usage formerly allowed
   the prefixing of for to the to; as, what went ye out for see? (Matt.
   xi. 8).
