Toneme deletion
toneme deletion
There are several cases of toneme deletion in Hausa:
If the initial syllable is light, it cannot host two tonemes of a melody. Thus, the first toneme of the melody is deleted, e.g. tʃí 'eat' + \LH (IMP) → tʃí 'Eat!'.
A floating L toneme is deleted in following cases: (i) when the root-final vowel to
which the floating L tone is attached is short, e.g. ʔàukú ‘happen’ + -Lwáː (NMLZ) → ʔàukúwáː ‘occurrence’, (ii) when the root-final long vowel carries L, e.g. ɽúfèː ‘close’ + -Lwáː (NMLZ) → ɽúfèːwáː ‘closing’, and (iii) when the root-final long vowel carries a sequence of H and L, e.g. tʃêː ‘say’ + -Lwáː (NMLZ) → tʃêːwá ‘saying’
A toneme can be deleted when its segmental carrier is deleted, e.g. Háruːnà → Háruː (proper name)
