Y-Epenthesis (1) (Southwestern Ojibwe)

Rule ∅ → y / [+SYL, +LONG] _ [+SYL, +LONG]
Abbreviation yep1
Type Synchronic phonological

Nichols calls this "T-Epenthesis," but this is assumed to be a misprint, since a) /t/ is not inserted, and b) another rule on the same page is also called "T-Epenthesis." This rule is listed in two parts; in addition to between long vowels, /y/ is also inserted after a vowel, before a vowel-initial conjunct central suffix (yep2).
