Nota accusativi is a grammatical term for a particle (an uninflected word) that marks a noun as being in the accusative case. An example is the use of the word in Spanish before an animate direct object: .
Officially, in Esperanto, the suffix letter is used to mark an accusative. But a few modern speakers use the unofficial preposition instead of the final .
In Hebrew the preposition is used for definite nouns in the accusative. Those nouns might be used with the definite article ( ). Otherwise, the object is modified by a possessive pronominal suffix, by virtue of being a within a genitive phrasing, or as a proper name. To continue with the Hebrew example:

This example is obviously a specialized use of the , since Hebrew does not use the unless the noun is in the definitive.
In Japanese, the particle (pronounced ) is the direct object marker and marks the recipient of an action.
In Korean, the postposition or is the direct object marker and marks the recipient of an action. For example:
is used when the previous syllable ( in this case) is closed, i.e. when it ends with a consonant ( in in this case).
is used when the previous syllable ( in this case) is open, i.e. when it ends with a vowel ( in in this case).
In Toki Pona, the word is used to mark a direct object.
Nota accusativi also exists in Armenian, Greek and other languages.
In other languages, especially those with grammatical case, there is usually a separate form (for each declension if declensions exist) of the accusative case. The nota accusativi should not be confused with such case forms, as the term is a separate particle of the accusative case.
