Fowler had much to see about the nominative ['I'] or the accusative ['me'] in apposition to the verb 'to be' — in other words, whether it should be 'It is I' or 'It is me'. He acknowledged 'I' as more pedantically correct, but came down ultimately in favour of the more colloquial 'me' as a matter of usage, augmented by an emphatic quality in the latter, largely influenced by French usage - C'est moi.
