pieza

Pieza is a feminine noun in Spanish that denotes a part, component, or item that forms part of a whole. It is widely used to refer to a piece of machinery, a manufactured component, or a spare part, as in pieza de repuesto or pieza mecánica. In manufacturing and engineering, a pieza is often a single element produced or machined to fit within a larger device.

In everyday language, pieza also designates a room or chamber, especially in some varieties of Spanish, where one might say una pieza for a bedroom or living room, though habitación or cuarto are more common in other regions.

In arts and culture, pieza is used for works such as a musical piece (pieza musical), a short theatre work (pieza teatral), or a sculpture, painting, or other artwork considered as a single piece. In games, sports, and popular usage, a chess piece is also referred to as una pieza (por ejemplo, la pieza negra).

Other common uses include jewelry pieces or artifacts: una pieza de joyería or una pieza arqueológica. In legal or administrative contexts, pieza can refer to a document or item within a case file, such as pieza probatoria or pieza procesal, forming part of the evidence or record.

Plural form is piezas for multiple items. The term is widely understood across Spanish-speaking countries, though nuance and frequency vary by region and context.
