I know Somali and can speak it well, though not the best. The problem is that I know some words but I don't know EXACTLY what they mean, I've just heard it used in so many different ways that I comprehend it 90% way from the context. For example I know how to use the word "ayaan" in somali but I don't know the definition. I know it's something good and cheery with luck involved and stuff like that but I can't pinpoint it. Obviously I know stuff like objects and animals those words are straightforward but the adjectives, ideas, and things that you have to describe are where the grey areas lie. Another word would be "Indho adeeg", I know exactly how to use that word but can't describe it.
