A plateau cannot be formed between a lexical tone and a phrasal tone; so in the sentence "kíri mu Bunyóró" 'it is in Bunyoro' there is downdrift, since the tones of "Bunyóró" are phrasal. But a phrasal tone can and frequently does form a plateau with a following high tone of either sort. So in "abántú mú Úgáńda" 'people in Uganda', there is a plateau from the phrasal tone of "tú" to the lexical tone of "gá", and in "túgendá mú lúgúúdó" 'we are going into the street', there is a plateau from the phrasal tone of "ndá" to the phrasal tone of "dó". Again there are certain exceptions; for example, there is no plateau before the words "ono" 'this' or "bonnâ" 'all': "muntú onó" 'this person', "abántú bonnâ" 'all the people'.
