| | Njaama Tone |
 | | Three things happen: (1) First, a low tone is inserted by default into the world mula, giving the whole word low vowels; (2) the pitchless prefix wa- is attached; and then (3) since all vowels must have a pitch, the nearest pitch spreads, that pitch being the low tone on the u vowel in mula. |
 | | Hostility aside, though, the definition of upstep is, shall we say, the phenomenon which occurs when two L tones which are associated with two separate tone bearing units (e.g., vowels) are separated, on the tonal tier, by a H tone which is associated with nothing (i.e., it's floating). |
 | | As a result, that floating H tone does one of three things: (1) Disappears, due to the OCP (two identical tones next to each other collapse into one tone on the tonal tier); (2) causes upstep; or (3) attaches (provided there's an empty tone bearing unit to attach to). |
