Hello, my name is Yusti Pérez. I created a "Conlang" called "Langanish" (Langanazo). I started writing at night on a notebook. Long story short, I developed the language basing it in "Spanish" but making regular changes depending on the "root word" you're referred to. That way, the learner doesn't have to learn vocabulary so zero since the vocabulary is generated from the "root word" going through a "Langanishation" process that makes it sound and be written different and gives other language vibes. I also developed a writing system, but I opted for the latin alphabet with a few variations. Finally, the grammar is an english-based one, still combinated with idioms and spanish sayings.
I hope you'll find it interesting!
