The first of the weekly illustrations and accompanying videos of a Cymraeg word this year!
Madarch: mushrooms
Madarchen: a mushroom
Madfall: lizard
Madfallod: lizards
Madfall is a variant of Mabddall (a blind son)
Mab: son
dall: blind
This peculiar name comes from the likeness to a blindworm/slowworm.
ymlusgiad: reptile
ymlusgiaid: reptiles
ymlusgo: crawl or slither
llusgo: to drag
ym:self (reflexive)
So ymlusgo (to crawl) is to self-drag, a reptile is a self-dragger!
