Etymology: Oarweed is a compound of "oar" and "weed," and the name refers to the shape of the seaweed's fronds. Its long, flattened blades look like the oars of a boat, which is the picture the first half of the name carries. The second half is the ordinary word "weed," used for any plant growing where people do not want it, and in this case applied to a large marine brown alga of colder coastal waters. The word is simple in construction, and its meaning is transparent once the two parts are known. Its strength lies in the image it preserves: a seaweed named after the tool used to propel a rowing boat, a pairing that makes the plant's form easy to picture.
