glijder

Glijder is a Dutch noun formed from the verb glijden (to slide) with the agent suffix -er. In standard Dutch, it most commonly refers to the slider of a zipper (rits). The glijder is the movable component that travels along the teeth of a zipper to open or close the garment, bag, or other item. The term is widely used in sewing, clothing repair, and textile manufacturing. When a zipper jams or breaks, replacing or repairing the glijder is a common maintenance task.

Beyond zippers, glijder can denote any part designed to slide within a guide or along a rail in mechanical contexts. This sense is less common in everyday language, and more specific terms such as glijlager (sliding bearing) or simply slider may be used depending on the industry.

Etymology and usage: The word is formed from glijden 'to slide' plus the agent suffix -er, yielding 'glijder' meaning 'one who glides' or 'slider'. The plural is glijders. The primary usage remains the zipper component, but the broader meaning appears in technical descriptions where sliding elements are discussed.

Related terms include rits, ritssluiting (zipper closure), and slider, which is the English loanword sometimes used in technical Dutch contexts.
