In order to y so as to
In order to y so as to se utilizan para expresar la finalidad, purpose en inglés. Vamos a ver estos dos y el contraste con to infinitive, además de so that.
1. To = In order to = So as to + INFINITIVE
Remember that in order to and so as to are more formal than to, but the meaning is the same. So depending on the situation, if formal or informal, you will use to or in order to/so as to.
Examples: I’m buying butter to make a cake (informal).
When the purpose is negative, we use “not“, in order not to and so as not to.
But we don’t use not to.
2. So that + Subject + Verb Example: if you are walking at night, wear white so that cars can see you.
So that means para que + subject (para que los coches te puedan ver). On many occasiones we use modal verbs after the subject, in this case “can“. Now it’s your turn. Practise with these sentences:
