is used in many constructions where strict grammarians prescribe I.
This usage is not so much ungrammatical as indicative of the shrinking range of the nominative form: me
began to replace I
sometime around the 16th century largely because of the pressure of word order. I
is now chiefly used as the subject of an immediately following verb. Me
occurs in every other position: absolutely
, and after prepositions, conjunctions, and verbs, including be
Almost all usage books recognize the legitimacy of me
in these positions, especially in speech; some recommend I
in formal and especially written contexts after be
and after as
when the first term of the comparison is the subject of a verb.
