This kana represents the sound 『ン』 (n) and is used in katakana for writing loanwords, foreign names, and onomatopoeia. It functions as a moraic nasal, which can appear at the end of a syllable or before another consonant, and its pronunciation may vary slightly depending on the following sound (e.g., like 'm' before 'p' or 'b'). For example: 『ペンを つかう』 (pen o tsukau, 'to use a pen').
