grammar notes for preposition

The often heard but misleading “rule” that a sentence should not end with a preposition is transferred from Latin, where it is an accurate description of practice. But English grammar is different from Latin grammar, and the rule does not fit English. In speech, the final preposition is normal and idiomatic, especially in questions: What are we waiting for? Where did he come from? You didn't tell me which floor you worked on. In writing, the problem of placing the preposition arises most when a sentence ends with a relative clause in which the relative pronoun ( that; whom; which; whomever; whichever; whomsoever ) is the object of a preposition. In edited writing, especially more formal writing, when a pronoun other than that introduces a final relative clause, the preposition usually precedes its object: He abandoned the project to which he had devoted his whole life. I finally telephoned the representative with whom I had been corresponding. If the pronoun is that, which cannot be preceded by a preposition, or if the pronoun is omitted, then the preposition must occur at the end: The librarian found the books that the child had scribbled in. There is the woman he spoke of.

MORE ABOUT PREPOSITION

What is a preposition?

Prepositions are a category of words that are placed before nouns and pronouns to create phrases that modify nouns, verbs, or adjectives.

A preposition is the first part of a prepositional phrase. The preposition is followed by an object, such as a noun or pronoun, as in outside the house.

Prepositional phrases indicate a relationship between words in a sentence. For example, in I exercised after dinner, after is the preposition in the prepositional phrase after dinner. Together, after and dinner tell you more about (modify) the verb exercised. They tell you when I exercised.

Prepositions and prepositional phrases are used to begin phrases that modify nouns, verbs, and adjectives. While they often follow the words they modify, but they have to, Before supper, I washed my hands. Before is modifying washed, describing when I washed my hands.

Why are prepositions important?

The first records of the word preposition come from around 1350. Preposition combines the prefix pre-, meaning “before,” and the word position, meaning “relative location.” A preposition usually (but not always) comes before a noun or pronoun.

Prepositions are often used for describing relationships of space (on, around, below) or time (before, after). They also describe other relationships, such as purpose (the pencil used for drawing; the pencil I draw with) or connection (Paul traveled with Jane; the person Paul traveled with).
