I have seen a tiger into negative sentence
grammar

I have not seen a tiger.

Explanation:

There are two types of changing any sentence into negative sentence.

A) With change in meaning: In this type of transformation the negative word (no,not, etc) comes after helping verb and the total meaning of original sentence reverse.

Consider an example

"He is Ram" changing this sentence into negative results "He is not Ram" which change the meaning of orginial sentence

B) Without change in meaning: In this type of transformation not only the negative word (no,not etc) comes after helping verb but also the parent word in sentence interchanges with a word in such a way that sentence doesn't loose its original meaning.

Consider an example

"This is the front door of my house" changing this sentence into negative results "This is not the back door of my house" which clearly indicates first and second sentence are pointing towards a single point.
