Here's my attempt at documenting the absurd history of my conlang's name changes due to various reasons. Maybe at some point I'll check what exactly every version meant, but I'm pretty sure this is accurate.

1. Mode (effect…type? Honestly the old ones were ridiculously vague and I apologize)
2. Si Me ("this-message cause", i.e. how it came to be)
3. Si Me Me ("this-message cause cause", i.e. the rules of message formation)
4. Mo Mo (me > mo, "cause cause"; the language was totally context-sensitive at the time so this name only really works in the context of talking about messages…but I used it anyway)
5. Momo (orthographic reform, specifically removed spaces (now optional))
6. Simomo (returned "si" because it didn't really work without it anyway)
7. Sitiomo (not sure what "tio" meant, but it was probably another causal word (like immediate cause))
8. Simeca (I think tio, mo > me, ca here)
9. Simemo (ca > mo (partly undoing the last version))
10. Zimemo (si > zi)
11. Zemo (if I recall, I decided "me" was unnecessary and changed zi to ze)
12. Zedimo (changed "mo" to have the reverse effect (meaning "effect" rather than "cause"), so it needs the "di" modifier to undo that)
13. … probably more names but it looks like I stopped for a while. I realized over this period that I should be clearer than just stating causality to properly describe a language.
14. Sita ("this-message kind-of-thing/type")
15. Sika (ta > ka)
16. si ka (orthographic reform, hyphenated "si-ka" version for other languages)

Thankfully, I'm a lot less indecisive about the names now, so I guess if there's a moral to this, it's that you shouldn't give up on finding the right name.
