Etymology
The word 'slider' is a transparent Modern English compound formed from the native Germanic verb 'slide' and the agentive suffix '-er'. The verb 'slide' itself descends from the Proto-Germanic slīdaną, which carries the core sense of gliding or slipping smoothly. This root is part of a wider Indo-European family related to concepts of slipperiness. The suffix '-er', one of the most productive in English for forming agent nouns, directly attaches to the verb stem to create a word meaning 'one who or that which slides'. The semantic logic is perfectly straightforward, with the modern specialized meanings for food and sports pitches being metaphorical extensions based on the smooth, gliding motion implied by the core morphemes.
