slitted

Slitted is the past participle and, when used attributively, an adjective derived from the verb slit. It describes something that has been cut with a long narrow incision or that features such openings. The base verb slit means to make a lengthwise cut, and its principal past tense forms are slit and, in some contexts, slitted when used as a past participle or descriptive modifier. Etymology traces to Old English slītan, with related forms in other Germanic languages.

Slitted is commonly used in discussions of materials, architecture, biology, and design. In materials and engineering, it describes objects that have narrow openings created by slitting, such as slitted metal sheets or slitted plastic components. In architecture and design, slitted windows, slitted screens, or slitted louvers refer to linear, elongated openings that control light or airflow. In biology and anatomy, the term can describe features that resemble narrow slits, such as slitted leaves or, descriptively, slitted pupils.

Usage notes and variants: slit is the base verb with the simple past tense slit; slitted is often preferred when the word functions as an adjective or when the past participle form is needed. The term may appear in technical writing, product descriptions, and descriptive prose.

Examples: The lanterns had slitted panels to diffuse light. The plant exhibited slitted leaves along the stem.
