Adposition agreement is a crucial aspect of language that many people overlook. It refers to the matching of prepositions or adpositions to their corresponding objects in a sentence. Adposition agreement ensures that the language is clear, concise, and grammatically correct. This article will cover the basics of adposition agreement and why it is essential.

What is Adposition Agreement?

In grammar, an adposition is a word that connects and shows the relationship between two words or phrases. It includes prepositions, such as “in,” “on,” “under,” “above,” “below,” and “over,” and postpositions, such as “ago,” “until,” and “since.” These adpositions serve to specify temporal, spatial, and other relationships between the words.

Adposition agreement requires that the adposition and its object agree in terms of case, gender, and number. In other words, the adposition must reflect the characteristics of the noun or pronoun that is its object.

For example, in English, we say “in the box” and “on the table.” The preposition “in” requires the object to be in the accusative case, while the preposition “on” requires the object to be in the nominative case.

Why is Adposition Agreement Important?

Adposition agreement is crucial because it ensures the clarity and precision of language. When the adposition and its object do not agree in case, gender, or number, the sentence can be ambiguous or even nonsensical.

For example, let`s consider the sentence “He walked on the table.” This sentence is nonsensical due to the mismatch of the adposition and its object. In this case, “on” is a preposition that requires a surface, while “table” is a noun that requires a position. Had the sentence read “He walked on the floor,” it would have been grammatically correct, clear, and precise.

Adposition agreement also plays a crucial role in different languages. For example, in Russian, adpositions require the object to be in a particular case, and failure to use the correct case can entirely change the meaning of the sentence.


Adposition agreement is a fundamental aspect of language, ensuring clarity, precision, and grammatical correctness. Adpositions connect and show the relationship between two words or phrases, and require that their object agrees in case, gender, and number. By following adposition agreement, we can avoid confusion, ambiguity, and nonsensical language.
