(7.47) Bumo Izon labial and alveolar plosives and implosives (Efere 2001)<br />

Plosives Implosives<br />

Labials bu¤bu¤ ‘rub (powder <strong>in</strong> face)’ ∫U@∫aI ‘yesterday’<br />

Alveolars Îç@Îç@ ‘cold’<br />

Mixed bI¤dE¤ ‘cloth’ Îa¤∫a¤ ‘swamp’<br />

<strong>The</strong> velar plosive /g/ and the labiovelar implosive /©∫/, however, may<br />

freely occur with members of both the plosive and implosive series, as shown <strong>in</strong><br />

(7.48).<br />

(7.48) Bumo Izon velar plosive and labiovelar implosive (Efere 2001)<br />

Velar plosive /g/ Labiovelar implosive /©∫/<br />

With same igo¤do¤ ‘padlock’ ©∫a@∫u ‘crack (of a stick break<strong>in</strong>g)’<br />

With different Îu@gç@ ‘to pursue’ ©∫o@da©∫o@da ‘ra<strong>in</strong> (hard)’<br />

∫u@gi@ ‘to wr<strong>in</strong>g (hand)’<br />

Why are /g/ and /©∫/exempt from harmony? Consider the <strong>in</strong>ventory of<br />

oral stops <strong>in</strong> this language, shown <strong>in</strong> (7.49).<br />

Intuitively, the labial and alveolar voiced plosive stops each have an implosive<br />

‘partner’, whereas the velar and labio-velar voiced stops have no counterparts.
