What adds a syllable to the end of word?

There isn't one specific thing that *always* adds a syllable to the end of a word. It depends on what you're adding and how it changes the pronunciation.

Here are some common ways to add a syllable to the end of a word:

* Suffixes: Many suffixes add a syllable. For example, "-ing", "-ed", "-er", "-est", "-ly", "-ness", "-ment", "-tion", etc. These change the meaning or grammatical function of the word.

* Plural endings: The plural ending "-s" or "-es" can add a syllable to words that end in a consonant sound.

* Adding vowels: Sometimes adding a vowel, like "-a" or "-o", can create a new syllable, especially in words that were previously monosyllabic. For example, "dog" becomes "doggo."

Important Note:

* Syllable count can change depending on pronunciation. For example, adding "-es" to "box" creates "boxes" (two syllables), but adding "-es" to "church" creates "churches" (one syllable).
