The Chinese word **局部 (júbù)**, meaning "part" or "local area," is a compound formed by combining two characters with closely related semantic meanings. The first character, **局 (jú)**, originally referred to a part, section, or bureau, and by extension implies a confined or partial scope. The second character, **部 (bù)**, means a part, division, or portion. Together in the **modifier-modified structure**, they create a tautological compound where both elements reinforce the same core concept of a "partial section," resulting in a term that specifically denotes a non-whole, limited part of a larger system or area, such as in "局部麻醉" (local anesthesia) or "局部问题" (a localized problem).
