Syllabically:
* Cit-i-zen (This is the most common way to divide it for pronunciation)
Morphologically (breaking down the word's structure):
* Cit-izen: This shows the root word "cit" (meaning "city") and the suffix "-izen" (meaning "inhabitant").
For word games or puzzles:
* Ci-ti-zen: You could break it down into three syllables if necessary.
* C-it-i-z-en: You could even break it down into individual letters, though this is unlikely to be helpful in most contexts.
Ultimately, the best way to divide the word "citizen" depends on your specific purpose.
