Inversion means putting the verb before the subject.
It is a literary technique in which the normal order of words is reversed, generally for emphasis
or special effect. It makes a sentence sound striking or unusual. It also sounds quite formal.
Sentences with inversion are less common in everyday English.
In a sentence with no special effect or emphasis, the normal order of words is retained.
Example 1 : I have never seen such a beautiful rose.
Example 2 : Never have I seen such a beautiful rose.
