Listen to how children on the island speak and you will hear the shift. More English, more Pidgin, a little less Ibani. Nobody decided it. It just happened, the way weather does.
That matters, because the language is not only words. It is jokes that do not translate, names that carry history, greetings that tell you who you are speaking to. When it goes, a whole way of understanding the world goes with it.
The remedy is not a conference. It is practice. Greet your elders in Ibani. Teach a child a proverb. Cook the dish and say its name properly. Learn three new words this week and use them before you forget.
Culture survives in the mouth long before it survives in a museum. Let us keep it there.
