How to write Louis in katakana
Japanese writes foreign names in katakana, one of its two alphabets, by sound rather than by spelling. Louis becomes ルイス, made of these parts:
| Katakana | Sound | Note |
|---|---|---|
| ル | ru | |
| イ | i | |
| ス | su |
You may also see Louis written ルイ (Rui). Both are used; ルイス is the more common spelling.
When you write a full name, Japanese puts a middle dot between the first and last name, for example ルイス・スミス for Louis Smith.
