α-Shortening, and again this allows the /ae/ to be targeted by PerfN and Resit
ablaut formatives.

7.3.1.16 A ugmented - CvCCv-, -CvCu Cv-, etc.

Verbs that take Augment -t- are all V-final (§5.1, §7.1), and I know of none
that begins with a full V. In this section I describe augment verbs that have a
medial full V, which may appear in the penultimate or antepenultimate
syllable. (I know of no verb with more than one medial full V). These verbs
share relevant features with other (non-augment) verbs that have a medial full
V (§7.3.1.7, §7.3.1.14).
Several subtypes must be recognized based on vocalism and stem-initial
treatment, but they correlate with stem-shape. I begin with verbs whose medial
full V occurs in a stem-initial closed syllable in the basic lexical
representation. All verbs of this type have u as the full V, most transparently in
the perfective system. A medial u can also be posited for the imperfective and
VblN forms, but except for imperatives and unsuffixed short imperfectives the
/u/ appears as a due to Medial V-Shortening before the CC cluster. The basic
shapes are middleweight -CUCCD- and superheavy -CuCCvCu-, plus
Augment.
