    The construction of the infinitive verbs with "zu"

    There are to forms of using zu (zu or um ...zu).

    1.The infinitive verb is widened with zu. Both are placed at the end of a sentence. 

    Ich kann bald lesen und schreiben. -> Ich hoffe, bald lesen und schreiben zu können.

    Willst du die Kirche besichtigen? -> Hast du Lust, die Kirche zu besichtigen?

     

    2. The construction with um ... zu differs. It is equivalent to the English construction "(in order) to" plus the infinitive of the verb. Um is at the beginning of the infinitive-sentence. 

    Esse einen Apfel, um gesund zu bleiben!

    Um dick zu werden, muss man viel essen.

    enlightenedPay attention, if you are using separable verbs."Zu" is placed between both parts of the verb.
