‘括入’ is a formal, written verb meaning 'to include' or 'to incorporate', typically used in technical, legal, administrative, or academic contexts. It combines the characters 括 (kuò), meaning 'to enclose' or 'to encompass', and 入 (rù), meaning 'to enter' or 'to bring in'. Together, they convey the idea of formally bringing something into a defined scope, list, category, or system.

This word is rarely used in everyday spoken Chinese—it sounds stiff and bureaucratic. You’ll encounter it most often in official documents, regulations, software interfaces, data processing descriptions, or scientific classifications—for example, when specifying which items are covered by a policy or which data points fall within a parameter. It implies intentionality and precision: not just casual inclusion, but deliberate, rule-based incorporation.
