The word **脑浆 (nǎojiāng)** is a compound noun formed through semantic combination, where **脑 (nǎo)**, meaning "brain," acts as the subject or location, and **浆 (jiāng)**, meaning "thick fluid" or "paste," specifies the substance. Thus, it literally translates to "brain paste" or "brain matter," specifically referring to the soft, gelatinous tissue of the brain itself. This formation is typical in Chinese for creating concrete, descriptive terms, where the first character denotes the object or organ, and the second characterizes its physical state or material. It is a graphic, anatomical term often used in clinical or violent descriptive contexts.
