The Editor's Manual
Grammar, usage, punctuation, and style resource for editors, writers, and learners of the English language.
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.
Prepositions express relations of time (“during the day”), space (“at the market”), and other abstract relations (“the secret of happiness”) between the parts of a sentence. Prepositional phrases comprise a preposition and its object.
A gerund is a verb form (“bake”) ending in “-ing” (“baking”) that functions as a noun. Just like a noun, a gerund can act as the subject or the object of a verb, or the object of a preposition.
Nouns are words used to identify people, places, objects, and ideas. Nouns can be proper or common, count or mass (or both), and concrete or abstract. Gerunds are verb forms that function as nouns.
Some verbs can take gerunds and infinitives as the object interchangeably (e.g., “start,” “love,” “prefer”). But certain verbs can take only infinitives (e.g., “need,” “plan,” “agree”), while others can take only gerunds (e.g., “finish,” “consider,” “suggest”).
Use “who” for the subject and “whom” for the object in a sentence. In everyday communication, “who” can replace “whom.” To choose between “who” and “whom,” a simple trick is to form a question and frame its answer.
An infinitive is the basic form of a verb. It is most often used with the word “to” (“to go”, “to win”, “to be”) and does not change with tense or subject. The infinitive can be used as a noun (subject or object of a verb), an adjective, or an adverb.
