Blue (Adjective)

Level 4:
Blue - Azul

While at first this looks like it comes completely "out of the blue," this is yet another case of a poorly matched word pair.

True, "Blue" looks nothing like "Azul," but it's very close, indeed, to "Azure" (a blue-cyan color on the HSV color wheel). Also, Azure/Azul can be seen in certain gemstone names, such as Azurite and Lapis Lazuli.

If you're not familiar with the English word, Azure, however, this makes Azul harder to pick up on. So, why not familiarize yourself with Azure a bit?

Boat (Noun)

Level 1:
Boat - Bote

Boat gets its Level 1 status based on being spoken, not on being written. However, there's not a lot of difference there, either.

"Boat" and "Bote" are pronounced the same way, excluding differences based solely on accent, but "Bote" looks like it is "Boat" spelled incorrectly.
