Why People Confuse Noisy And Noisey

The confusion happens because many English adjectives ending in -y are formed from words that change spelling.

For example:

Some writers assume:

noise + y = noisey

But the correct spelling changes the final e:

noise + y = noisy

The letter e is removed before adding -y.
