Steven Bird (1999b) exam<strong>in</strong>es <strong>the</strong> success of phonemic tone mark<strong>in</strong>g for a<br />

Grassfields Bantu language called Dschang. It uses tone to dist<strong>in</strong>guish lexical items<br />

<strong>and</strong> some grammatical constructions. See table 1 below:<br />

Table 1. Analysis of tone comprehension errors <strong>in</strong> Dschang<br />

Zero Mark<strong>in</strong>g Full Mark<strong>in</strong>g<br />

Lexical errors 0 3<br />

Grammatical errors 18 11<br />

Bird observed that <strong>the</strong> same grammatical errors were made <strong>in</strong> both <strong>the</strong> zero<br />

marked text <strong>and</strong> <strong>the</strong> full marked text though errors were less frequent <strong>in</strong> <strong>the</strong> full<br />

marked text. 2<br />

Lexical m<strong>in</strong>imal pairs are <strong>the</strong> most frequently cited reason for justify<strong>in</strong>g a tonal<br />

orthography. Never<strong>the</strong>less, Bird’s experiments demonstrated that, for those<br />

languages, full tone mark<strong>in</strong>g is worse for readers with regard to lexical identification<br />

than zero tone mark<strong>in</strong>g. He fur<strong>the</strong>r states (Bird 1999b) that:<br />

The tonal alternations <strong>in</strong> this language [Dschang] are postlexical, i.e. part of<br />

<strong>the</strong> process of utter<strong>in</strong>g words <strong>in</strong> <strong>the</strong> context of a phrase. In effect, <strong>the</strong> tone patterns<br />

serve to “glue” words toge<strong>the</strong>r <strong>in</strong>to phrases. (In this respect <strong>the</strong> system functions<br />

like English phrasal <strong>in</strong>tonation, which is not marked orthographically but for <strong>the</strong><br />

limited use of punctuation symbols such as <strong>the</strong> comma.)<br />

Therefore lexical m<strong>in</strong>imal pairs alone are not sufficient reason for mark<strong>in</strong>g<br />

lexical tone.<br />

Those with an <strong>in</strong>terest <strong>in</strong> orthography design for tonal languages would do well to<br />

read Steven Bird’s evaluation of <strong>the</strong> contributions <strong>and</strong> weaknesses of early<br />

orthography experiments by Efik, Mfonam, <strong>and</strong> Bernard (Bird 1999b).<br />

Tonal orthography design <strong>in</strong> M<strong>and</strong>en languages should<br />

be based on empirical tests<br />

Most publications <strong>in</strong> M<strong>and</strong>en languages, by foreign NGOs with which this<br />

analyst is familiar, mark tone only on <strong>the</strong> second <strong>and</strong> third person plural pronouns – if<br />

at all. Contrarily, <strong>the</strong> orthography promoted by <strong>in</strong>digenous readers of M<strong>and</strong>en<br />

languages <strong>in</strong> <strong>the</strong> grassroots <strong>Nko</strong> literacy movement marks tone fully. 3<br />

2 Similar results were observed between <strong>the</strong> full-marked orthography of <strong>the</strong> <strong>Nko</strong> script<br />

<strong>and</strong> <strong>the</strong> present near zero marked orthography <strong>in</strong> <strong>the</strong> <strong>Roman</strong> script.<br />
