Expressing Purpose: to, in order to, so that, for
Introduction
Expressing purpose means explaining the reason why an action is done. There are several structures in English to express purpose, each with specific rules. Understanding these structures helps you write and speak more precisely.
1. To + Infinitive (Most Common)
Used when the subject of both verbs is the same. Example: "He went to the library to study." "She called me to invite me to her party."
2. In order to / So as to + Infinitive (More Formal)
Used for formal contexts. "In order to" can be used with a different subject in its negative form. Example: "He studies hard in order to succeed." "She left early so as not to miss the train."
3. So that + Subject + Modal (Different Subjects)
Used when the subject of the purpose clause is different from the main clause. Use "can/will" for present, "could/would" for past. Example: "I gave him my number so that he could call me." "She spoke loudly so that everyone could hear."
4. For + Noun / Gerund
"For" + noun indicates the purpose of an object. "For" + gerund can also express purpose. Example: "This brush is for painting." "He went to the shop for bread."
