He came to after being rendered first-aid

In English, a preposition usually pairs with a verb forming a phrasal which carries a different meaning all together.

In this post, the phrasal verb I am going to introduce is 'came to'.

Normally you will construct a sentence such as the following:
He came to my house to borrow the Science notes.

As a phrasal verb, however, you will make a sentence such as the one shown below.

The unconscious man came to after being given first-aid by a nurse.

The phrasal verb 'came to' in the above sentence means 'regained consciousness'.
