Which is correct Sarah is beeter than me or Sarah is better than I?

Answer 1

"Sarah is better than I" is the traditional answer (even aside from the misspelling of "beeter"). The reason is that, by convention, "than" when following a predicate adjective in the comparative form is normally supposed to be interpreted as subordinate conjunction that begins an adverbial clause of the form, "than {explicitly stated subject} {implicit form of the verb 'to be' appropriate to the stated subject} {basic form the adjective that, in its comparative form, precedes 'than'}", where each phrase between curly brackets defines an explicitly stated or implicit word as indicated. Thus, the sentence given is to be understood, with the implicit words between square brackets, as "Sarah is better than I [am good]"

However, note that the above rule is not necessarily followed when the verb in the independent clause of the sentence is a transitive verb and the comparative adjective follows an object of that verb rather than a predicate adjective, as in the example sentence. In that instance, there are two different possibilities: "My mother likes my sister better than I" means that my mother likes my sister better than I like my sister, but "My mother likes my sister better than me" means that my mother likes my sister better than my mother likes me.
