[20] /ɦ/ serves as a source for murmur, of which there are three rules:[21] The table below compares declensions of the verbs [kəɾʋũ] ('to do') and [kɛ̤ʋũ] ('to say').
If to a formal or historical root of /kəɦe/ these rules are considered then predicted, explained, and made regular is the irregularity that is [kɛ̤ʋũ] (romanized as kahevũ).
