• This term can only be used when followed by a noun or noun phrase. It cannot be used as a standalone pronoun. Examples:
  • Correct:

    この色(いろ)が好(す)きです。 ― Kono iro ga suki desu. ― I like this color.

    • A noun follows kono.
  • Incorrect:

    このが好(す)きです。 ― Kono ga suki desu. ― I like this ...

    • There must be a noun in place of the "...", as this is the adnominal, or attributive form, incapable of standing independently.
    • Using kono in this way is comparable to using English the without a noun after it (*I like the.).
  • Correct:

    これが好(す)きです。 ― Kore ga suki desu. ― I like this.

    • A pronoun is used in the stead of the attributive, resulting in the desired meaning of 'this', with no verbal reference present nor required as to the identity of the object.
• Almost always spelled in hiragana as この.
