We grew up with Tolkien. Our kids grow up with walkthroughs.

The line that stopped me was about moss.

Sarah, a teacher, had been testing our app with her class of six and seven year olds. She wrote to us with the sort of feedback every founder hopes for and half dreads. The children kept asking to watch more. They loved the real photographs. The boys thought Una looked a little too girly. All useful, all noted.

Then she added something I had not been looking for. She said she liked how descriptive the language was, and she quoted two lines back to us. Tall trees reaching high up into the sky. A green moss that spreads like a carpet on the forest floor. She said she could see the children picking it up without noticing, because it runs through everything, and hopefully, one day, putting it into their own writing.

I read that line three times.

We did not build that language as a teaching tool. We built it because it is how you describe a forest properly. It is craft. It never occurred to me that a child might not hear language like that anywhere else.

She is right, though. They mostly do not.

What happens when children stop hearing rich language

I grew up with Alice in Wonderland and Tolkien. Someone read them to me, slowly, at bedtime, doing the voices. The words were strange and long and often beyond me. That was the point. You grow into language you do not yet own. You reach up to it.

My son's generation grows up with game walkthroughs and memes. Fast, flat, functional language. Brilliant in its own way, and I am not sneering at it. But it is not moss spreading like a carpet on a forest floor.

Sarah wrote again a few days later. She had shown another class a clip about animals in Romania. When the children heard that a newborn bear cub is the size of the teddy bear on their own bed, the room filled with gasps. She counted at least five wows. One child said, did you hear that, that is amazing. That is what a vivid, concrete image does to a six-year-old. It is not decoration. It is the thing that makes them lean in.

I am not here to make any parent feel guilty about this. I am a solo mother. Some nights I do not have a bedtime story left in me, and the tablet does the work I cannot. Most parents I know are in the same place. Time is the thing nobody has, and reading aloud is often the first thing that goes.

So the rich language has to come from somewhere. If it is not always going to come from us, at the end of a long day, then it can at least live inside the things our children already choose to watch.

People will tell you language always evolves, and that this shift is simply part of it. Maybe. But there is a difference between language changing and language shrinking. A smaller vocabulary is not a new dialect. It is fewer words for the same world.

Children think in the words they have. Give them more words, and you give them more world. Take the words away and the world gets smaller and flatter, one clip at a time.

Why we keep the language rich on purpose

This is why we do not simplify how Una speaks. She uses real, textured, descriptive language, all the time, whether or not a child understands every word yet. We could have written flatter, safer sentences that never stretch anyone. We chose not to. The understanding follows the words, not the other way round. That is how it has always worked, since long before any of us had screens.

Unomundi is a cultural-discovery app where children aged 6 to 12 explore countries and cultures through stories, games, and conversations with Una, a warm AI guide. The countries and cultures are the point. The language is how we carry them into a child's imagination.

Sarah noticed it before I did. She saw children reaching for words they had only just met, the way I once reached for the words in a bedtime story I did not fully understand. That is the whole job, really.

The line that stopped me was about moss. I want a generation that still has words like that.
