303 5-3.41.2 -:- As in the case of zero complement vowel-drop, vowel length is more properly a morphophonemic process than a suffix, but as it occurs to verbalize noun roots, stems, and themes, it is here included with the other verbalizers. When vowel-length verbalization is followed by a suffix that requires a preceding consonant, the length may be somewhat reduced, or the vowel in question may revert to simple length, or it may remain somewhat lengthened; length appears to vary from one speaker to another. A timed spectrographic analysis of texts con- taining vowel length verbalization is needed to define the length in different contexts. In this study some examples containing the morpheme of vowel-length verbali- zation show the notation /:/ before a consonant-requiring suffix, if more than one vowel-length was perceived to occur. If only one vowel-length was perceived, the notation /:/ is usually omitted from the transcription, the presence of a vowel before a consonant-requiring suffix being sufficient to indicate the underlying pres- ence of the vowel-length morpheme in that context. This suffix is in complementary distribution with -ka- ~ -ja- verbalizer, never occurring after -na possessive/locational. Examples:
