ITS

Definition
  1. Possessive Determiner (Tính từ sở hữu):

    • Belonging to or associated with a thing, animal, or entity previously mentioned or easily identified: "its" indicates possession by a non-human or non-personal subject. It is the possessive form of "it."
    • Note: Unlike "it's" (a contraction of "it is" or "it has"), "its" has no apostrophe.
  2. Possessive Pronoun (Đại từ sở hữu):

    • The thing or things belonging to or associated with a non-human or non-personal entity: "its" can function as a possessive pronoun, though this usage is rare and typically occurs in formal or literary contexts (e.g., "its own" or "its rights"). More commonly, "its" is used as a determiner before a noun.
