From sona pona, the Toki Pona wiki

The sitelen sitelen word glyph for tonsi was added in 2020.[1][2] It is derived from the word glyph for kule (kule) and the syllable glyph for to (TO), with the bottom part being the same as in the glyphs for meli (meli), mije (mije), and the newer variant of mama.[3]
