I'm looking for information about the etymology of the word'snail'.

The word'snaill' is a compound word made up of two parts: s-nail and -ll. S-nail comes from the Old English word snæl, which meant "a nail". This word was derived from the Proto-Germanic *snailaz, which in turn came from the Proto-Indo-European root *sei- "to pierce" (see also seel).
