Noun particle

A noun particle is any morpheme that denotes or marks the presence of a noun. They are a common feature of languages such as Japanese and Korean.

Korean particles
Korean noun particles are postpositional, following the word they mark, as opposed to prepositions which precede the marked word.

Korean noun particles include the subject particle i/ga (이/가), the object-marking particle eul/reul (을/를), and the topic-marking particle eun/neun (은/는), all of which show allomorphy.

Japanese particles
Like Korean, Japanese noun particles follow the noun being marked, and can serve any of several functions in a given sentence.

In this example, "e" is the noun particle for "sūpā" ("supermarket"). This particular noun particle denotes direction towards a place, being "supermarket."

The three noun particles ("wa," "ga," and "o") all serve different functions:
 * "wa" - topic marker ("hirugohan" - lunch)
 * "ga" - subject marker ("watashi" - I)
 * "o" - object marker ("piza" - pizza)
