English prepositions are words – such as of, in, on, at, from, etc. – that function as the head of a prepositional phrase, and most characteristically license a noun phrase object (e.g., in the water).[1] Semantically, they most typically denote relations in space and time.[2] Morphologically, they are usually simple and do not inflect.[1] They form a closed lexical category.[3][4]
Many of the most common of these are grammaticalized and correspond to case markings in languages such as Latin.[5]: 48 For example, of typically corresponds to the genitive.
