Words in Luganda commonly belong to one of three patterns (other patterns are less common): (a) toneless, e.g. "ekitabo" 'book'; (b) with one high tone, e.g. "ekibúga" 'city'; (c) with two high tones, e.g. "Kámpalá" which link together to make HHH, i.e. or [Kámpálâ. (At the end of a sentence, the final tone becomes a falling tone, i.e. , but in other contexts, e.g. when the word is used as the subject of a sentence, it remains high: "Kámpálá kibúga" 'Kampala is a city'.)
