Etymology
1. According to Kroonen, a strong verb back-formed from the iterative verb *sluppōną, from a Proto-Indo-European *slewp- (“to slip, glide”), and cognate with Lithuanian įslupti (“to slip into”), Latvian šļupt (“to slip”).
2. However, de Vaan reconstructs the root as coming from earlier forms *sleuppaną < *sleubnaną, and derives it from a Proto-Indo-European *slewbʰ- (“to slip, slide”), comparing Latin lūbricus (“slippery”). If this connection is accepted, the root may have only belonged to a late western Indo-European dialect.
