Origins
Unknown. Some possibilities include: * from Etruscan, due to the -rno- element as also in vīburnum, alburnus; * from a Mediterranean substrate word of the form *lapa or *laba “rock” (Latin lapis), in reference to the terrain where the plant grows; * if the first element is Latin (through folk etymology or otherwise), this might be labrum (“a lip”) or lābor (“to glide down”) + -urnus depending on the length of the vowel. For the former derivation compare Old English smǣre (“lip(s)”), Danish smære (“clover”), Icelandic smæra (“bermuda buttercup”). Compare labrūsca.
