Spontus is a Breton word I learnt recently that means scary or terrible, as in spontus eo an amzer hiziv (the weather is terrible today). It doesn’t sound like it comes from a Welsh or Cornish root, and I wondered where it came from.
According to the Wikeriadur spontus comes from the word spont (to faint/wake with terror) plus the suffix -us. Unfortuantely it doesn’t say where spont comes from. Does any one have any ideas?
