How many spelling rules are represented in the sentence "The rabbit hopping through the swaying grass"?

The sentence "The rabbit hopping through the swaying grass" illustrates three distinct spelling rules that relate to the formation of the words used.

Firstly, the word "hopping" demonstrates the rule concerning doubling the final consonant when adding a suffix to a one-syllable verb that ends in a single vowel followed by a consonant. In this case, "hop" becomes "hopping" as the 'p' is doubled.

Secondly, the word "swaying" features the rule pertaining to the addition of suffixes to verbs ending in 'y.' In instances where a verb ends in 'y' preceded by a consonant, the 'y' changes to 'i' when adding a suffix. However, since 'sway' is adding the 'ing' suffix, it retains the 'y.'

Lastly, the general rule regarding silent letters can be observed in the word "through," where the 'gh' is silent and contributes to the unique pronunciation of the word.

These three examples collectively illustrate the application of distinct spelling rules within the sentence, confirming that there are indeed three spelling rules represented.
