The aphorism “English words don’t end in u,” is frequently invoked by spelling teachers as an aid in spelling such common words as, blue, clue, cue, due, flue, glue, hue, and true. The silent final e also rescues the following words from the onus of ending in u: construe, continue, ensue, imbue, and issue.
The only two native English words that end in u are the pronouns thou and you, but they probably shouldn’t count because they really end in ou.
There remain 50 or so “English” words that do end in u. I put English in quotation marks because most of these u-words obviously came undigested from some other language, most from French. I’ve arranged them in three groups. I won’t provide definitions for the first group because they are fairly common.
1. U-words you may have come across, depending on your age and reading habits
2. U-words with special applications
acajou: A tree related to the cashew.

bijou This French word for “jewel” was popular as a name for movie theaters.
eau:This French word for “water” appears on bottles of eau-de-cologne.
ecru: the color of unbleached linen.
Jehu: a fast driver. In some old novels it’s used as a generic name for a coachman. The reference is to Kings 9:20: “And the watchman told, saying, He came even unto them, and cometh not again: and the driving is like the driving of Jehu the son of Nimshi; for he driveth furiously.”
kinkajou: a fruit-eating quadruped of Central and South America, allied to the raccoon.
landau: A four-wheeled carriage, the top of which, being made in two parts, may be closed or thrown open. Aficionados of period novels will be familiar with this word.
