llon

See also: -llon

Welsh

From Middle Welsh llonn, from Proto-Brythonic *llonn, from Proto-Celtic *londos (compare Old Irish lond (“fierce”)),^[1] of uncertain ultimate origin; Stokes suggests a comparison with Sanskrit रन्धयति (randhayati, “to torment, destroy”), from Proto-Indo-European *lendʰ- (“to cook”).^[2]

llon (feminine singular llon, plural llonnau, equative llonned, comparative llonnach, superlative llonnaf)

Welsh mutation

llon	lon	unchanged	unchanged
Note: Some of these forms may be hypothetical. Not every possible mutated form of every word actually occurs.
