The Chinese word **入境** is a compound formed by combining two characters: **入** (rù), meaning "to enter," and **境** (jìng), meaning "border" or "territory." It follows a standard verb-object grammatical structure where the first character denotes the action and the second character denotes the target of that action. Thus, the literal meaning is "to enter a border," which semantically specializes to refer specifically to the formal act of **entering a country**, commonly used in contexts like immigration (e.g., 入境手续, entry procedures). This formation is typical of modern Chinese vocabulary, where concise two-character compounds are created for precise conceptual expression.
