Menomini summary: iterative regressive (righttoleft) assimilation of
long high [ATR] vowels ([I:] and [U:]) with following high [+ATR] vowel
([i], [i:], [u], and [u:]). Short high [ATR] vowels ([I] and [U]) and long or
short low [ATR] vowels ([A] and [A:]) are transparent; low [+ATR] vowels
([a] and [a:]) are opaque.
As a first attempt at a constraint system, we consider only the assim
ilation process, ignoring opacity and transparency. We assume that the
assimilation is driven by Agree[ATR] AE Ident[ATR]. Since low, short,
or [+ATR] vowels are never altered by assimilation, but long high [ATR]
vowels are, we have:
Id[+ATR], Id[low], Id[shortV] AE Agree[ATR] AE Id[high], Id[longV], Id[ATR]
The lowestranked constraints will occasionally be omitted from tableaus.
Note that because Vowel Place is never altered in order to obtain agreement,
we also have an undominated Ident[VPlace] constraint in the ranking,
which we will also omit from tableaus.
In order to enforce an assimilation directionality, we could consider using
