Luis ᚌ | ||
Luis (ᚂ) is the second letter of the Ogham alphabet, derived either from luise "flame" or from lus "herb". Its Proto-Indo-European root was either *leuk- 'to shine' or *leudh- 'to grow'. Its phonetic value is [l].
The Auraicept na n-Éces glosses the name as cairtheand "mountain-ash", i.e. "rowan" (Modern Irish caorthann). The associated verse is : Li sula "lustre of eye" The Auraincept interprets this as "delightful to the eye is luis, i.e. rowan, owing to the beauty of its berries".
