Seaweed

8th October 20268th October 2026 By Simon

In this post we’re looking into words meaning dulse, seaweed and related things in Celtic languages.

Dulse (Palmaria palmata) is a reddish-brown type of seaweed which is sometimes eaten in Ireland, Scotland, Wales and other places. The English word dulse was borrowed from Irish and/or Scottish Gaelic. It is also written dilisk, dillisk, dilsk or dulce.

Words marked with a * are reconstructions.

Other words from the same roots include fjör (vitality, sprightliness, vigour, energy, fun, merriment, life) in Icelandic, fur (pinewood) in Swedish, quercia (oak) in Italian, pērkons (thunder) in Latvian, and fir and cork in English, and possibly the words below [source].
