Does a word get spelled differently if you add suffix?

Yes, a word can often be spelled differently when you add a suffix.

Here's why:

* Suffixes can change the pronunciation: Adding a suffix can change the sound of the word, and this change in pronunciation can be reflected in the spelling. For example, "hope" becomes "hoping" with the suffix "-ing". The "e" is dropped because the sound of the word changes.

* Suffixes have their own spelling rules: Some suffixes have specific rules about how they are added to words. For example, the suffix "-ing" is often added to verbs, but there are rules about how to deal with final consonants.

Examples:

* Drop the final "e": "hope" + "-ing" = "hoping"

* Double the final consonant: "run" + "-ing" = "running"

* Change the "y" to "i": "happy" + "-ness" = "happiness"

* Add a "u" before a suffix starting with "a, e, i, o, or y": "argue" + "-able" = "arguable"

It's important to learn the spelling rules for different suffixes to ensure you are adding them correctly.
