In the West Midland, the prefix _i-_ or _y-_ is seldom used for the past participle, whilst the East Midland admits it more freely.

In the third person singular of the present tense, the West Midland favours the Northern suffix _-es_ or _-is_; whilst the East Midland favours the Southern suffix _-eth_.

The suffix _-us_ appears to be altogether peculiar to West Midland, in which it occurs occasionally; and the same is true of _-ud_ for _-ed_ in the preterite of a weak verb.

The very remarkable poem called _The Pearl_, and three _Alliterative Poems_ by the same author, were first edited by Dr Morris for the E.E.T.S.
