  • She came to the city to look for work. (Why did she come to the city? To look for work.)
  • He sat down to rest. (Why did he sit down? To rest.)

We can also use 'in order to' or 'so as to'.

  • She came to the city so as to look for work.

'So as to' and 'in order to' are more common before verbs like be, have, know etc.

  • He raised his voice so as to be heard.
  • He got up early in order to have enough time to pack.

Before a negative infinitive, we normally use 'so as' or 'in order'.

  • I am leaving now so as not to be late. (NOT I am leaving now not to be late.)
