Syllables are units of pronunciation. They are the individual parts of a word that are pronounced together. For example, the word "water" has two syllables: "wa" and "ter".
Apostrophes are used for a variety of purposes, including:
* Contractions: Combining two words into one, like "don't" for "do not".
* Possessives: Showing ownership, like "John's book".
* Missing letters: When a letter is omitted, like "can't" for "cannot".
The use of an apostrophe is determined by the grammatical function of the word, not the number of syllables.
