What is the difference between DIy and ngItlh? It seems like the former is used for things that get stuck or jammed on their own parts, like a door and its frame, while the latter is for two things that are distinct and can theoretically move apart from each other. But I'm not sure I've really captured the difference there.

What's the semantic difference between HIr and ngam? Does HIr imply being held in place? Which word would be better used for, say, a gecko walking on a wall, sticking to it with its feet? My guess is that it would fall under the category of ngam.

HIr is stative and ngam is active. The thing sticks (ngam) because it is stuck (HIr).
