Weak vowels

horsES

Both a central [ə] and a high front [ɪ] are widely observed as the realizations of the regular plural suffix. The former is reported to be exclusive to CanE and BahE, the latter to TobC, Baj and SurC (to the extent that these creoles have traces of this suffix); SAmE, NEngE and NfldE have both variants quite regularly, and in all other dialects [ɪ] is normal but schwa is also possible under specific circumstances.
