Names

Because proper names don't have symbols that are widely understood, they get written in a particular way.

Each sound/letter of a name gets written out with any sitelen pona character that starts with the same sound/letter.

The finished name then gets enclosed by a cartouche - a border that wraps around the name as a whole:

ma [kasialasanasinawenteloa]

Which characters get chosen is up to preference and can hold personal value. Here is the exact same word written in two different, equally valid ways:

jan [pilininsateloen]

jan [ponailotawaesun]

Note that names in Toki Pona don't appear on their own. A regular Toki Pona word, which describes the concept of the namee, goes in front.
