Both “than I” and “than me” are grammatically correct, since “than” can be used as either a preposition or a conjunction. “Than I” is seen more often in formal usage.
“I” is a subject pronoun, while “me” is an object pronoun. In formal styles, use “I” in a compound subject and “me” in a compound object. “Me” is generally preferred in comparisons and after the “be” verb.
Use “you and I” as the subject and “you and me” as the object in a sentence. Avoid hypercorrection. “You and me” is used more often after the “be” verb and in comparisons.
A simple subject is the main word or phrase that a sentence is about. A complete subject is the simple subject and any words that modify or describe it.
Various grammatical forms can function as the subject in a sentence. The subject can be a noun phrase, a noun clause, or a prepositional phrase.
Use the correct form of the verb with singular and plural subjects. To ensure subject-verb agreement, identify the subject and check whether it is singular or plural. Some subjects may appear plural but be singular.
One of a group is singular (“One of them is” not “are”). But when “one of the” is followed by “who” or “that,” check who is being described: the entire group or one of them.
“Either” is grammatically singular and used with singular verbs (like “is” and “has”) in formal usage. In informal usage, the word may be treated as either singular or plural.
“None” may be either singular or plural, depending on whether you mean “not one” or “not any.” To refer to the individual members of a group, use a singular verb; for the entire group, use a plural verb.
Use “I” instead of “me” when it forms part of the subject (“You and I can work on this together”). When pronouns are joined using “or” or “nor” to form the subject, the verb should agree with the part closest to it (“Either you or I am right”).
