i. An available TBU, the second member of the cluster will dock to that syllable Similar to Table
5-1 A, see examples containing disyllabic L and M
2
toned words in §5.3.2.1 and§5.3.2.2
ii. Completely specified tonal melodies, the tonal melody will be blocked from having an effect, but
the register will remain active and dock to the following syllable Similar to Table 5-1 B and C, see examples containing disyllabic M
2
H words in §5.3.2.3 and monosyllabic H in §5.3.2.4
iii. A monosyllabic morpheme, a falling contour will usually be formed Similar to Table 5-1 D, see
examples containing monosyllabic morphemes in §5.3.2.5 and §5.3.2.6
While the evidence for the activity of the tonal register was inconclusive in §5.3.1.3, clear evidence for this
activity, despite blockage of the tonal melody, will be seen below in §5.3.2.3. The difference in
noticeable effect is due to the difference in register of the mobile tone: the H has a h register while the M
1
has a l register. In the sections that follow, the same environments that were discussed with the M
1
-H cluster above will be illustrated for the mobile M
1
: disyllabic L toned morphemes, disyllabic M
2
toned morphemes, disyllabic morphemes with M
2
on the first syllable and H on the second, monosyllabic H toned morphemes and monosyllabic L toned morphemes. In addition, an example of a monosyllabic M
2
toned morpheme will be discussed. For each environment, the similarities and differences between the effects of floating a H tone
versus a floating M
1
tone will be discussed.
5.3.2.1 Juxtaposition of the Floating M
1
with a Disyllabic L Toned Word
The first environment to be discussed is the juxtaposition of a disyllabic word with two level low tones. This behavior was exemplified above in the discussion concerning mobility and is parallel to the
behavior of the M
1
-H cluster. Recall that in the case of the disyllabic Low toned word, there is only one tonal melody and one tonal register associated with the two syllables; therefore, there is room to
accommodate a second complete TRN without the formation of a contour. The case of the M
2
-M
1
cluster was demonstrated in example 2 and will be repeated here as 37. The M
2
links to the cluster’s original
272
host syllable and the M
1
docks to the first syllable of the following word 37c which surfaces with the M
1
on its first syllable and the L from its lexical specification on its second syllable. 37

The first TBU on the targeted morpheme is considered available because it is part of a disyllabic morpheme which hosts only one TRN; the morpheme has two TBUs but only one TRN. In 37c, two l-registers are
linked adjacently to the same morpheme, so merger is motivated by the OCP 37d. Each syllable in the
273
final representation hosts one tone and all three tones which were lexically supplied are expressed as level tones.
The L-M
1
mimics the behavior of the M
2
-M
1
when juxtaposed with a disyllabic Low toned word. The first syllable of the juxtaposed word will surface with a Mid-High tone while the original sponsor
syllable of the cluster surfaces with a level Low tone. The example from 3 above is repeated here as 38. As has already been demonstrated, when the two morphemes are in context, the UAC links one tone to
each TBU irrespective of the tone’s lexical origin 38c which each surfaces with a level tone. 38

In 38c two l registers are brought into close association by the new linkage and merger as is motivated by the OCP gives the surface structure 38d.

In the case of juxtaposition of the M
2
-M
1
and L-M
1
clusters with disyllabic Low toned words, the docking of the M
1
floating tone is analogous to the behavior of the floating H of the M
1
-H contour in a similar environment as was described in
§5.3.1.1. The schematization that was offered there can be expanded to include the floating M
1
. The only differences in the schematization are the generalizations of the tonal feature specifications to a completely generic T. The subscript x and y are used to indicate the
tonal origin. 39

The behavior of the floating tones in these examples is in agreement with what would be expected to be motivated by the UAC with a left to right directionality. At this level of representation, it is identical to
standard Autosegmental Phonology.
