We're going to have a look at what happens when we add -ed, -er, -est and -ing to root words ending in 'y' with a consonant before it.
Here we have an example:
If we add -ed to the word copy it becomes copied. The y is changed to 'i' before ed, er and est.
But what happens when we add -ing?
The word copy becomes copying. We do not change the 'y' to 'i' because this would result in iing! There are two exceptions to this rule: skiing and taxiing.
