Please note: this word is pronounced FYOOkoid.
It's to do with seaweed.

In the nineteenth century there was a craze for seaweed. People collected it, dried it, and placed it in albums. And if it made people happy, why not?
Sadly, sea weed is much less admired today, and being at all fucoid would I'm afraid involve having a very very bad hair day, or else require either a strong dose of deodorant or an immediate change of diet.
Surely best avoided, if possible.
Thing Not To Be Today: fucoid. This word describes seaweed of the genus Fucus, which is found on almost all the coasts of the world.
(Fucus seaweed may not be rare or fragrant, but it can be used as fertiliser, and in glass and soap making. Bacteria found on the surface of Fucus seaweed have recently been found to be able to combat MRSA. It has also been used in thalassotherapy, in which people are smothered in seaweed-based gunk (to no known scientific benefit, but never mind).)
The word fucoid comes from the Greek phukos, which means seaweed.
