What’s the most challenging aspect of creating a conlang for you, and how do you overcome it?

For me, it's keeping the language consistent while making it feel natural. Phonology is tricky—I’ll design a sound system I like, but then words start feeling awkward. I’ve started recording myself speaking to catch what doesn’t flow well.

Grammar is another challenge. I want structure without making it too rigid. Writing short texts in the language helps me see what works.

Vocabulary takes forever. I get stuck making words feel organic. Using root words and affixes has helped me expand it more easily.

What about you? What’s the hardest part, and how do you deal with it?
