Lasinen

Lasinen is a Finnish adjective meaning made of glass or glass-like. It is formed from the noun lasi (glass) with the suffix -inen, a productive way to form material-based descriptors. The term describes objects whose material is glass or whose surface has a glassy appearance.

The word is commonly used with nouns naming tangible items, for example lasinen ikkuna (glass window), lasinen pöytä (glass table), or lasinen astia (glass dish). It can also describe surfaces or architectural elements, such as lasinen pinta (glass surface) or lasinen katto (glass roof). Like other Finnish adjectives, lasinen agrees with the noun in number and case, for instance lasinen talo (a glass house) and lasiset talot (glass houses).

As a standard -inen adjective, lasinen inflects according to Finnish grammar. The opposite materials are expressed with other adjectives such as puinen (made of wood) or kivinen (made of stone). A related descriptor is lasimainen, meaning glassy or glass-like in texture, and is often used to describe appearance or feel in a broader, sometimes metaphorical sense.

Etymology and usage context: Lasinen derives from lasi, and appears across everyday language, design, architecture, and product labeling to indicate glass composition or a glassy quality. It contrasts with terms describing other materials and with more general descriptors of transparency, which may use different roots or phrases depending on nuance.
