sition in these constructions and demands the objective case. And there is the objection that as I constructions are overly formal, even pretentious. In short, both constructions are defensible and both are subject to attack. When you want to play it safe, use the as I construction, but throw in the verb to make it a clause: She is just as proud as I am.

personal pronouns after forms of be
That must be him on the phone. No, it must be he. Traditional grammar requires the nominative form of the pronoun following the verb be: It is I (not me); That must be they (not them), and so forth. Nearly everyone finds this rule difficult to follow. Even if everyone could follow it, in informal contexts the nominative pronoun often sounds pedantic and even ridiculous, especially when the verb is contracted. Who would ever say Its we? But constructions like It is me have been condemned in the classroom and in writing handbooks for so long that there seems little likelihood that they will ever be entirely acceptable in formal writing.

The traditional rule creates additional problems when the pronoun following be also functions as the object of a verb or preposition in a relative clause, as in It is not them/they that we have in mind when we talk about crime in the streets nowadays, where the plural pronoun serves as both the predicate of is and the object of have. In this example, 57 percent of the Usage Panel prefers the nominative form they, 33 percent prefer the objective them, and 10 percent accept both versions. Perhaps the best strategy is to revise these sentences to avoid the problem. You can say instead They are not the ones we have in mind, We have someone else in mind, and so on.

personal pronouns after but
Should you say No one but I read the book or No one but me read the book
? If but is a conjunction in these sentences, you should use the nominative form I. If but is a preposition, you should use me. So which is itconjunction or preposition? Although some grammarians have insisted that but is a conjunction here, they have had to admit that the objective form me is appropriate when the but phrase occurs at the end of a sentence, as in No one has read it but me. And in fact there is a strong case for viewing but as a preposition in all of these constructions. For one thing, if but were truly a conjunction, you would expect the verb to agree in person and number with the noun or pronoun following but. You would then say No one but the students have read it, but you normally say No one has read it. What is more, a conjunction cannot be moved to the end of a clause, as in No one has read it but the students. You can tell this because you cannot use the similar conjunction and in this way. That is, you cannot say John left and everyone else in the class. For these reasons it seems best to consider but as a preposition in these constructions and to use the objective forms of pronouns such as me and them in all positions: No one but me has read it. No one has read it but me. These recommendations are supported by 73 percent of the Usage Panel when the but phrase precedes the verb and by 93 percent when the but phrase follows the verb.

personal pronouns after except
Just like but, except in the sense of with the exclusion of or other than is generally viewed as a preposition, not a conjunction. Therefore, a personal pronoun that follows except should be in the objective case: No one except me knew it. Every member of the original cast was signed except her.
