slide

slide: [OE] Slide comes from a prehistoric Germanic *slīd- ‘slide, slip’, which also produced English sled, sledge, sleigh, and slither [OE]. Its ultimate source was the Indo-European base *slei- or *lei-, a prolific source of words for ‘slide’. A version with -dh- on the end lies behind slide, and is also responsible for Greek olisthánein, Lithuanian slysti, Latvian slīdēt, and probably Welsh llithro ‘slide’. A version suffixed -b- produced English slip, and one ending in -g- has spread throughout the Slavic languages, giving Russian skol’zit’, Czech klouznouti, etc, all meaning ‘slide’.
