How To Use The Word "Like"
Many people object to the use of like as a conjunction, as in the following sentence:
He’s behaving like he owns the place.
Like has been used in this way since the 15th century, and by many respected writers, but it’s still considered unacceptable in formal English. You should use as if or as though instead, e.g.:
He’s behaving as if he owns the place.
