Prepositions - In / At /OnProfª Maria Glalcy Fequetia Dalcim

Prepositions A preposition is a word used to

link nouns, pronouns, or phrases to other words within a sentence. Prepositions are usually short words, and they are normally placed directly in front of nouns. In some cases, you’ll find prepositions in front of gerund verbs.

A preposition describes a relationship between other words in a sentence.

Consider the professor's desk and all the prepositional phrases we can use while talking about it.

You can sit before the desk (or in front of the desk). The professor can sit on the desk (when she's being informal) or behind the desk, and then her feet are under the desk or beneath the desk. She can stand beside the desk (meaning next to the desk), before the desk, between the desk and you, or even on the desk (if she's really strange). If she's clumsy, he can bump into the desk or try to walk through the desk (and stuff would fall off the desk). Passing her hands over the desk or resting her elbows upon the desk, she often looks across the desk and speaks of the desk or concerning the desk as if there were nothing else like the desk. Because she thinks of nothing except the desk, sometimes you wonder about the desk, what's in the desk, what she paid for the desk, and if she could live without the desk. You can walk toward the desk, to the desk, around the desk, by the desk, and even past the desk while she sits at the desk or leans against the desk.
